Sunday, July 11th, 2010
Amy Marie Le asked:


1.) A gas barbecue grill uses propane gas. The propane is stored in a rigid tank. What happens to the pressure of the propane when the tank is left outside on a very hot summer day? What about on a cold winter day?

2.) How does the speed of the molecules of a gas change when the gas is heated?

I DON’T GET IT
Bottled propane is used in areas away from natural gas pipelines for cooking and heating, and is also the source of heat in most gas barbecue grills. Propane burns in oxygen according to the following balanced chemical equation.
C3H8(g) + 5 O2(g) 3 CO2(g) + 4 H2O(g)
Calculate the mass in grams of water vapor produced if 3.25 mol of propane is burned.
