Chemistry. PLEASE HELP
If we believed that the molecules of a gas move around fairly rapidly, we can use this to explain all of the following EXCEPT why adding more gas increases the pressure. why most of the volume of the gas sample is taken up by the gas molecules. why the gas molecules do not ...

An ideal gas is contained in a cylinder with a volume of 5.0 102 mL at a temperature of 30.C and a pressure of 710. torr. The gas is then compressed to a volume of 38 mL, and the temperature is raised to 827C. What is the new pressure of the gas? torr

An ideal gas is allowed to expand from 6.00 L to 45.0 L at constant temperature. By what factor does the volume increase? ? Number The pressure will Increase by that factor or decrease by that factor? If the initial pressure was 105 atm, what is the final pressure?

Physics
A 4 liter sample of a diatomic gas with γ =1.4 confined to a cylinder, is carried through a closed cycle. The gas is initially at 1.00atm. and 300K. First, its pressure is tripled under constant volume. Then it expands adiabatically to its original pressure. Finally the ...

A piston pump containing 2 liters of nitrogen gas at 3000 psia (absolute) pressure empties its entire contents into a 10 liter pressure container. Before the transfer of gas the 10 liter container already contained nitrogen gas at 100 psia (absolute) pressure. Assuming ...

a 2.50mL sample of dry air in a cylinder exerts a pressure of3.00atm at room temperature. without changing the temperature, a piston is moved until the pressure in the cylinder is reduced to 1.00atm. what is the final volume of the gas?
