described as the progressive gradual rise of the earth’s surface temperature thought to be caused by the alterations to the greenhouse effect and responsible for changes in global climate patterns. The greenhouse effect is the absorption of energy radiated from the Earth’s surface by carbon dioxide and other gases in the atmosphere‚ causing the atmosphere to become warmer. This whole process occurs naturally and has kept the Earth’s temperature about 59 degrees Fahrenheit warmer than it would otherwise

burner until its temperature measured anywhere from 95-99C. The hot water was then placed in the calorimeter and soon joined with 25 mL of cold water. The temperature of the 25 mL of cold water (from the tap) was measured and was added to the hot water‚ making sure that the lid was closed and that the thermometer was inserted into the hole at the top. The temperature of the mixture of the hot and cold water was taken and recorded in a spread sheet along with the initial temperature of both the hot

Fizz Time What is the Effect of Temperature on Chemical Reaction? Vonda Thornton Biology B4 10th Abstract The purpose of this project is to see if the scientist can measure the effect of temperature on the rate of a chemical reaction by using Alka-Seltzer tablets and different temperatures of water. It is hypothesized that the Alka-Seltzer tablet will dissolve the fastest in the Hot Tap Water because of the higher temperature. The Effect of Temperature on a Chemical Reaction? The
