Effects of Antifreeze on the Boiling Point of Water Lab Purpose: The purpose of this lab is to see how the boiling point is effected by adding antifreeze and to discover how this happens. Brief Background: The concepts used in this lab are intermolecular forces, vapour pressure/vapour pressure reduction and boiling point elevation. Intermolecular forces are weak forces of attraction and repulsion between particles/molecules etc.. By adding the antifreeze, the intermolecular forces got stronger. Vapour
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
is not a compound if you added one extra unit of oxygen it would still remain as air. Solutions can be in gaseous, liquid or solid states. Some examples of solutions in different states are: Liquid state Tea with sugar, Sea water (salt water), Antifreeze, Vinegar, Household cleaners, Soda water, alcoholic drinks, blood Gaseous state Air Solid state Bronze, White Gold, Steel, Stainless steel, Cast iron, Solder Water has good properties when it is used as an engine coolant. It has a good heat...
Introduction Someday in the near future the world as we know it will be covered in snow and ice. Accurate, scientific calculations predict that by the end of the century, humans will be forced to live in the Arctic. In order for humans to be cable of living in these harsh climates, homo sapiens will need to develop new characteristics to their bodies. There will be three main body systems that will have have to be altered so the human population can survive, the integumentary, circulatory, and digestive
living in in low temperatures around 0˚C with areas of ice that can be -1.9˚C (DeVries, 1971). The ability for Arctic fish to thrive in such a low temperature environment is made possible by a class of proteins called Antifreeze proteins. Antifreeze proteins (AFPs) and Antifreeze glycoproteins (AFGPs) are polypeptides that are biosynthesized in animals, plants and fungi that prevent ice crystal formation (Griffith & Ewart, 1995). The most widely accepted mechanism for the prevention of ice formation
Background Infromation In Cambridge England, in 1820 a man by the name of Reverend W. Cecil was explaining to fellow scientists and inventors how an internal combustion engine worked. All of his fellow colleagues just laughed at him and told him it could never be done. In 1860 Jean Joseph E'tienne Lenoir made Cecil's idea come to life by building the first practical internal combustion engine. Three years later in 1863 Lenoir built one of the worlds first gas engine cars. Ignition System
Write down how scientists think the antifreeze gene evolved. Scientist think the antifreeze gene evolved after there was a mutation occurred during the duplication of the original gene. 5. Antifreeze proteins are found in icefish blood. Explain how the antifreeze proteins help the icefish survive in the Antarctic Ocean. The simplest answer is that the antifreeze doesn’t allow the icefish’s blood to freeze in the cold temperature hence the name
Colligative properties are the physical changes that happen when you put a solute in a solvent. The ratio of the number of solute particles are a contributing factor, but not the types of particles. There are four main properties that are affected by this solute mass ratio, which include depression of freezing point, elevation of boiling point, lowering in vapor pressure, and osmotic pressure. Every kind of liquid basically has a freezing point, they just vary in temperature. Water for instance
Thermochemistry is the study of energy changes that occur during chemical reactions and changes in state. There are two different processes that have to do with the absorption and release of heat. In the endothermic process, the system picks up heat, as the surroundings lose heat. In the exothermic process, heat is released to its surroundings. Heat either goes in or goes out. We are going to make ice cream and we are going to identify which of these two different processes is used. Materials •
In the United States, 80-90 percent of children receive most vaccines. When parents opt their children out for vaccines, they increase the risk of outbreaks. Parents opt out of vaccinating their children for a variety of reasons, like health concerns, religion, allergic reactions, but mostly being misinformed. Vaccinations can save a child’s life and can protect future generations. A child should have all vaccinations before they enter public schools because they are safe, effective, can save time

what can you do to help protect your vehicle from the elements? Here are four things you can do to prepare and protect your vehicle for the harsh winter ahead. 1. Check Your Engine Coolant Engine coolant or antifreeze is the first thing you need to check before the winter rolls around. Antifreeze will keep your engine from freezing when the temperatures drop. You can buy a kit from your favorite auto parts store that will tell you if you have the proper amount of coolant mix to keep your engine from
I chose the death of Matthew Podolak. Matthew suddenly became sick and ended up hospitalized. Furthermore, Matthew began having back spasms and was treated for kidney stones at the local ER. Several weeks after this, Matthew was rushed to the hospital for dizziness and loss of balance where he died soon after. Due to there being lack of evidence of foul play at the time of death, it was ruled “manner undetermined.” Shortly before this, Matthew was diagnosed with depression and was given medications
Have you ever seen anyone around your school, community, or even workplace smoking inside? It makes you look twice due to public places not allowing people to smoke inside anymore since 2010 in Michigan (http://www.mml.org/). What you might be seeing is an e-cigarette or “Vape”. These electronic, vapor devices starting getting popular with teengers (and some adults) in 2012, the percentage of users has over doubled since 2011 (http://www.cdc.gov/). There are hundreds of brands of e-cigarettes and
Poisoning is illness caused by eating, drinking, touching, or inhaling a harmful substance. The damaging effects on a child's health will vary depending on the type of poison, the amount of exposure, the duration of exposure before treatment, and the height and weight of the child. These effects may range from mild to very severe or even fatal. ExitCare ImageMost poisonings take place in the home and involve common household products. Poisoning is more common in children than adults and is often
The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example
Rosalin was a single mother of two who was accused of poisoning one of her children with antifreeze. Being that the Toxicologist did not have the proper test to detect the condition of the women’s baby like they do now years later, they could not determine the actual cause of death which they thought turned out to be Methylmalonic Acidaemia (MMA)
from across the country. However, by that time 353 patients had received the “Elixir” during a 4-week period resulting in more than 100 deaths (including children), about a 30% fatality rate. It was found that Diethylene Glycol, a chemical used as antifreeze, is a deadly poison. GCP Principles violated: Although there were no GCP guidelines or federal regulations demanding safety testing for drugs in 1937, the sulfanilamide elixir case violated a number of GCP principles. • The first GCP principle
e-cigarettes, such as NJoy and Smoking Everywhere contain detectable level of tobacco-specific carcinogen, nitrosamines. Furthermore, e-cigarettes by Smoking Everywhere were found to contain diethlyene glycol, a common ingredient in automotive antifreeze and break fluid ...
organic compound with the formula (CH2OH)2. Monoethylene glycol (MEG), also known as ethylene glycol (EG) or simply glycol, is a diol mostly used for the production of polyester fibers and polyethylene terephthalate (PET) resins. It is also used in antifreeze applications and in pharmaceuticals and cosmetics. MEG is conventionally produced through the hydrolysis of ethylene oxide (EO), which itself is obtained via ethylene oxidation. Molecular structure: (Sources: Wikipedia, American Chemistry Council
