The Effect of Temperature on Air Pressure :: science

The Effect of Temperature on Air PressureDESCRIPTION My project consists of a series experiments to determine the effect of air squash in a given environment at various temperatures. The experiments I chose to conduct are 1) Heat an ordinary emerge behind on a animated plate and then putting the can upside down in cold water to see the effect of a fast change in temperature. 2) Partially full milk jug with hot water, put the cap on tightly, and let it sit for one moment to see the effect of a slow change in temperature. 3) Setting a gloomy piece of paper on fire and then putting it inside a waxy bottle. Before the flame goes out, a pealed hard-boiled egg will be placed over the opening. PROBLEM The problem is to determine the effects of air pressure at different temperatures. Since we cannot see air, we will attempt to determine if air exerts a force? HYPOTHESIS My hypothesis for 1) the experiment with the pop can is that the can will crush because of a drastic change in tempe rature. 2) the experiment with the milk jug and the hot water is that the milk jug will go on the same. 3) the experiment with the egg and the bottle is that the egg will not be sucked in the bottle. PROCEDURE For the first experiment the mental process is 1) Heat an ordinary pop can on a hot plate. 2) After about fifteen minutes take the can off the hot plate and put it turned in a pan of cold water. 3) Record my observations on a piece of paper. 4) Write my conclusions in my science fair logbook. For the second experiment my procedure is 1) Get an empty gallon milk jug at room temperature. 2) Heat to water to just before the boiling point on a hot plate. 3) Fill the milk jug about quarter of the way with hot water. 4) Put the lid on tightly 5) Wait one hour and record my observations and conclusions. For the third experiment my procedure is 1) Get a medium sized bottle. 2) Peel a hard boiled egg. 3) Light a small piece of paper on fire and put it inside the bottle. 4) Before th e flame goes out put the pealed egg over the opening of the bottle. 5) Record my observations on a piece of paper.
