INTRODUCTION TO ANTIFREEZE!: Antifreeze is a common chemical product that helps to keep the engines of the car stay cool. It is a combination of the chemical Ethylene glycol or Propylene glycol, which is 50%, and 50% water. Antifreeze is used during the winter & summer, to keep the car engine stay cool and running, and to achieve the freezing and boiling point depression, depending on the weather. Antifreeze allows the engine fuel to fully vaporize and burn better with less transmission. It also allows keeping the engine keep clean and operating efficiently as the car goes. CHEMICALS FOUND IN ANTIFREEZE!: Antifreeze is mainly a product that is made from chemical. Antifreeze contains chemicals that are very harmful and can cause health problems. The most harmful chemical substances that it contains are: Ethylene …show more content…
• Animals may take in any spilled antifreeze, causing themselves harm. • Inhalation of antifreeze can also cause severe headache & dizziness. • If antifreeze is spilled into the environment, it can have severe impact on marine life. Since, glycol demands for lots of oxygen, it can remove much of oxygen from the water. • The glycol from the spilled antifreeze release ammonia gas into the environment which is very strong and sometimes harmful and can cause skin, eye, and nasal irritation. Ammonia gas can also be very corrosive and can be flammable, if exposed to heat. ALTERNATIVES FOR ANTIFREEZE!: There are many ways in which we can help to minimize the risk of antifreeze. Because antifreeze containing harmful chemicals is very harmful and effects the environment, there are other best alternatives. We can reduce the amount of antifreeze that is put into the car engine. There are some antifreeze products that are made to help the engine as well as benefit the environment. These products are not harmful, have no taste or smell, and are very safe to
Procedure: A sand bath was set atop a hot plate set at power level 5, while a 10 mL round bottom was prepared with the addition of 14 (0.33 mL) drops of olive oil and 1 mL of cyclohexene. Once the contents of the 10 mL round bottom were mixed thoroughly, a boiling chip was added, and the round bottom was attached to a reflux condenser apparatus. The reflux was run for 20 minutes starting at the point in time when the mixture within the round bottom flask (that was submerged in the heated sand bath) began to boil. While the running the reflux, a 5 ¾ inch Pasteur pipette was obtained and clamped vertically with the tip facing downward. A small amount of glass wool was placed inside of the pipette and pushed down to block the narrowing end by a wooden boiling stick. A total of 100 mg (0.100 g) of celite was weighed out and was carefully added into the pipette as an additional layer atop the glass wool stopper.
Climate change increases the carbon dioxide levels in oceans. The increased CO2 causes shifts in ocean conditions, rising sea temperatures, rising of sea levels, etc. The increase of oceanic temperatures causes the melting of sea ice. The model shows this as climate change has an arrow going to sea ice melting. Sea ice is essential to Harp Seals. They depend on sea ice as a platform for pupping, molting, and resting (Kovacs, 2015). The Harp Seal pups stay immobile on ice packs for the first twelve days of their life to gain fat. Sea ice decline is resulting in less Harp Seal pups being born and surviving. The model shows this, because sea ice
...ls, it does not only affect the size of seal population but also it affects the Inuit people because it decreases the amount of seal oil and seal pelts being produced, and it also causes species that depend on baby seals to have a loss in their diet too. The seal population may not seem like it is diminishing however at this rate, the baby seals are faced with the possibility of becoming extinct. If the seal hunt was to continue at this frequency and with global warming also playing a major role into the death of seals as ice glaciers are melting, the population of seals can become extinct within the next few decades. Each year, there are hundreds of thousands of baby seals killed by the Canadian government and even though, the government is making profit from this industry, they failed to consider how is poses a significant long-term threat to their whole specie.
Refrigeration is the process of cooling down a space or thing below normal environmental temperature. Food preservation is vital in today’s day and age. From the meats to the dairy, everything needs to be kept at room temperature, cold, or frozen. People even like to make themselves cold and frozen by using air conditioning. But, it does make you wonder “how” and “when”. How did refrigeration become such an important invention and how did people survive without it? When did our ancestors realize it takes the cold to keep their food preserved and looking fresh? We now have fridges that have an automated ice machine and touch screens.
The stunning amount of diversity found in antifreeze proteins is evident of a fascinating evolutionary story. Exploring the phylogenetic and molecular data from different species of cold-water fish is a common starting point for determining the origins of antifreeze proteins. Antifreeze proteins can be divided into two groups, the AFPs and AFGPs. Of the AFPs, there are currently four known types: I, II, III and IV (Cheng et al., 1998). By examining...
Harmfull Effects of Ocean dumping include animals in danger with trash in their habitat, as well as contamination of public waters.
The product was made from 4-methylcyclohexanol. The chemical, 4-methylcyclohexanol is used in industrial settings. In 2014, West Virginia was exposed to this chemical in drinking water. Since this chemical is used to wash coal of its impurities, it was unsafe to drink the water as well as take a shower (CNN). Similarly, 4-methylcyclohexanol has a strong smell which may cause people to have symptoms like vomiting, skin irritation, and trouble breathing. Diesel is also replaced by 4-methylcyclohexanol (National Geographic).
What is cryobiology? It is "the study of the effects of freezing and low temperatures on living organisms" (Read, 1999). While the main focus of cryobiology is on living organisms (as suggested above), cryobiological techniques have been expanded to include treatment of nonliving things as well. This addition of non-living objects has expanded the focus to not only include plants, animals, and humans, but also to include machinery and other metal objects.
...and MEA. These chemicals are said to be linked with breast cancer, skin rashes, estrogenic, hormone disruptor, linked to liver and kidney cancer, and irritates the eye.
The Gulf of Mexico oil spill has had an extremely negative effect on the surrounding wildlife and ecosystem. The oil spread across the gulf contaminating any living organism that came into direct or indirect contact with it. The oil cuts off the ability of oxygen from the air to move into the water which directly harms fish and other marine wildlife that require that oxygen. The dispersant that the BP is using to try and break up the oil moves the slick into the entire water column which contaminates the ocean floor which would most likely not have seen any damage if it wasn’t for the use of these dispersants. More than 400 species that live in the Gulf Islands and marshlands are at risk and as of November 2 s...
An extended amount of exposure to FCM’s, or food contact materials should not be ignored for several reasons. Toxins, such as formaldehyde, a substance proven to cause cancer, have been approved by the FDA. Formaldehyde is frequently used, admitting low levels in plastic bottles used for sodas or tableware. Formaldehyde is an organic compound. It is the simplest form of aldehyde, also known by its systematic name methanal. Its similarity and relation to formic acid gives this substance its common name. In addition, other chemicals, such as bisphenol A, tributyltin, triclosan, and phthalate, that recognized for its distribution of hormone production, have been found in FCMs.
I will take a closer look at icing conditions on aircraft and give examples of icing related accidents. Body Icing, or ice buildup on the wings, is a particular problem for aircraft. When ice builds up on wings, it can disrupt airflow, robbing an airplane of lift and can decrease its angle of attack, which keeps it in the air. Wind tunnel and flight tests have shown that frost, snow, and ice accumulations (on the leading edge or upper surface of the wing) no thicker or rougher than a piece of coarse sandpaper can reduce lift by 30 percent and increase drag by up to 40 percent. Larger accretions can reduce lift even more and can increase drag by 80 percent or more.
Many hazardous pollutants escape from the internal combustion of the engine. Conventional gas powered vehicles use irreplaceable fossil fuels to run. When burned, these fossil fuels create numerous toxins like carbon dioxide (Larminie 246). Carbon dioxide is considered the main greenhouse gas that creates the foundation for global warming (hybridcars.com, pollutants). This harmful pollutant may not have a serious effect on people at first, but it does have consequential effects on the environment that in turn put people in danger (Nutramed.com). The major consequence caused by global warming is the rise in average temperature. This results in a domino...
Life changed immensely in the 20th century as air conditioning and refrigeration systems became more efficient and controllable. Air Conditioning and Refrigeration play important roles in providing human comfort, food processing, storage, and many other industrial processes. We chose this topic because our life would be difficult without AC and Refrigeration. This paper will talk about the history of air conditioning and refrigeration, the role of engineers in designing and building it, people’s life before and after air conditioning and refrigeration, and finally Applications in the area of achievements and future developments.
Everyday, alarming amounts of toxins are released into the atmosphere. Over the recent years global climate change, better known as “global warming” has become a worldwide problem facing our planet, and as the world becomes continuously warmer, the effects that climate change will pose to our planet and to the people who live on this earth, will be detrimental.
