Temperature Changes During the Addition of Sulphuric Acid and Sodium Hydroxide Solution Aim To investigate the temperature changes during the addition of sulphuric acid and sodium hydroxide solution. Introduction In this experiment we are using sodium hydroxide, sodium hydroxide, sulphuric acid. We are trying to find out how much acid it takes to neutralise alkaline. But there are many things that could effect my final result and I think that the main thing will be measuring the acid
Investigating Temperature Change when Different Volumes of Acid and Alkali are Mixed Prediction ========== My prediction is that the biggest temperature change will be when there are equal amounts of H+ ions and OH-, this is because create an optimum mixture for the ions to neutralise each other. Apparatus ========= v Empty plastic yoghurt cup v thermometer v Hydrochloric Acid v Sodium Hydroxide v Two measuring cylinders [IMAGE] Diagram =======

Affecting factors Ø The concentration of Copper Sulphate Solution (CuSO4) Ø The amount of Iron filings (Fe) used I have chosen to experiment using the 1st factor I will have to change the concentration of the Copper Sulphate Solution (CuSO4) Prediction
Task 4 “Midwest” Population – Home to 61 Million States – They include; Illinois, Indiana, Michigan, Wisconsin, Missouri, and Minnesota Temperature Expatiations Between 1900 and 2010, the average air temperature increased by more than 1.5°F. Temperatures are going to keep increasing across the Midwest, with the highest increases in average temperature expected in northern areas. Southern states will definitely experience more hot days, with a lot of days over 95°F and a couple days below 65°F
1. (10 points) There's many examples of Global Climate Change. Choose two of the 4 processes listed below and explain the evidence available as to how this process is contributing to climate change. A. Sea level rise- The temperatures around the globe rise, the oceans start to warm up and water expands, the ice caps and glaciers start to melt, and more precipitation starts to fall falls instead of snow. These are some of the causes for sea levels rising. Recorded by the Department of Ecology, the
and how it is affected. We could change: Room temperature Surface area Amount of water Use a lid Insulate around it Colour of tin We could measure / observe: Amount of time Temperature We will change: Surface area We will measure / observe: Temperature (every minute for 5 minutes) Our question is: Does surface area effect the rate of heat loss? We will keep these the same: Colour of tin Room temperature Amount of water Use a lid Insulate
are vital aspects to our environment and it is necessary that we take care of them. On another note, global warming is an issue that is having effects on almost all aspects of our environment. Global warming itself means a gradual increase in the temperature of our Earth’s atmosphere over large periods of time. There is evidence that global warming has occurred in the atmosphere, however, now we are beginning to see its effects in the world’s oceans, as well. Though some may not see the connection that
dependant variables that I will keep the same will be the height of the tin can above the wick. I will keep this the same because different heights can effect the heat that is transferred to the tin can and into the water, therefore altering the temperature change. I will use the same tin can so that the experiment is fair and that different cans may be of different thicknesses so allowing different amounts of heat through. I will keep the amount of water that I put inside the tin can, the same for
The Effect of Temperature Change During the Dilution of a Strong Acid Introduction According to the Brønsted-Lowry acid-base theory, an acid is a reactant that loses a hydrogen ion to another reactant. A strong acid is when virtually all the molecules of the acid ionises in water. In this experiment, the strong acid used was hydrochloric acid. This acid is formed when gaseous hydrogen chloride reacts with water according to the equation: When in solution, the hydronium and chloride ions formed
coursework we are investigating the rates of reaction and he effect different changes have on them. The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. We are studying the affect of changing concentration of Na2S2O3 Solution and dilute HCl. I believe these variables will affect the rate of reaction: · Surface area · Pressure · Temperature · Catalyst · Concentration Concentration ============= If the concentration
Ocean Thermal Energy Conversion (OTEC) is the process of converting the ocean waters temperature difference at different depths into usable energy. From the solar heated upper depths of the ocean to the cooler depths below 2,000 feet a 40 degree temperature difference must be maintained to generate electricity. This is a relatively new and unheard of source of energy. Many people are not aware of the many benefits of OTEC and the impact it will have in the future as the use of fossil fuel conversion
carbohydrate or protein. The temperature change in water is caused by the absorption of heat given off by the burning of a known mass of food. Based on the change in temperature, you can calculate the amount of energy in food. If the room heats up more, this will not have an affect on the results because the water is hotter and so the results will not be higher than usual. It just means that the results will be the same but the initial starting temperature of the water will higher. Carbohydrates
the Caribbean Sea, Puerto Rico has a tropical marine climate, little seasonal temperature variation and always lots of sunshine. Because of its location, nearer to the equator than Norway, the island reaps the benefits of an annual average temperature of a whopping 80 degrees (http://dominicaonline.com/puertorico/prchstry.html). With a huge coastal plain on the north side of the island, and moderate temperature changes year round, agricultural cultivation is bountiful. Sugarcane, bananas, pineapples
avalanches. The fundamentals of how these snow masses occur, what to look for when testing and just all-together prevention. The basic chemistry behind a slab avalanche is when one layer of snow does not bond to the layer below it. Any kind of temperature change, fresh snowfall, the weight of a person, all can cause the slab to break free from the lower layer. The formation of a slab is possible in many ways. One way is for the snow to develop a crust and then there be more snowfall. Since snow doesn’t
Frankenstein - The Humanity of the Monster Sometimes, in novels like Frankenstein, the motives of the author are unclear. It is clear however, that one of the many themes Mary Shelley presents is the humanity of Victor Frankenstein's creation. Although she presents evidence in both support and opposition to the creation's humanity, it is apparent that this being is indeed human. His humanity is not only witnessed in his physical being, but in his intellectual and emotional thoughts
affects the time it takes for a drink to cool down. · Prediction My prediction is that the more the thickness of the insulation is increased the longer the drink will take to cool down. I also predict that for every two layers added the temperature change will go down by about 2oC. I do not predict that all of my results will follow a line of best fit exactly as that would be very hard to achieve but they will probably have a trend. There is a possibility of getting one or two anomalous
Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another, because of temperature changes. This can take place by three processes. These three processes are known as conduction, convection, and radiation. When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while others
maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996). Metabolic rate is directly linked to the core temperature in an animal. An ectotherm, or cold blooded animal, warms its body mainly by absorbing
with different temperatures. The resistance will be tested at approximately every 10 degrees, with a range from 80 C down to 30 C, and these results will be recorded. After recording the results, the experiment will be repeated at a total of 3 times, this is so we can get an average that should be correct and accurate. Scientific Knowledge: Thermistors are thermally sensitive resistors and have, according to type, a negative (NTC), or positive (PTC) resistance/temperature coefficient.
