Here's the actual problem:
A cylinder with initial volume V contains a sample of gas at pressure p. The gas is heated in such a way that its pressure is directly proportional to its volume. After the gas reaches the volume 3V a
A sample of ammonia gas with a volume of 7.0 mL at a pressure of 1.68 atm is compressed to a final volume of 2.7 mL at constant temperature. Use the ideal gas law to calculate the final pressure.
a. 100 atm
b. 2.2 atm
c. 1 atm
d. 4.4 atm
One mole of nitrogen and three moles of hydrogen are injected into a container of volume 10 dm^3 at 298 K. What are the partial pressures and the totalpressure? (Note: "^" means "to the exponent".)
The problem is this....
A gas with a volume of 4.0L is contained is a closed container. Indicate the changes in pressure when the volume undergoes the following changes at a constant temperature.
A. The vloume is compressed to 2 L.
B. The vloume is allowed to expand to 2 L.
C. The volume is copmressed to .40 L.

The specific heat of a gas at a constant pressure is 1.70 times the specific heat at a constant volume. Find the specific heat at a constant pressure. Universal gas constant= r= 8.31 J(mol K)
Show that the pressure exerted by a Fermi gas at absolute zero is
p = (2NEf)/(5V)
where N is the total number of particles, Ef the fermi energy and V is the volume.
((If you need to use the relation for the mean energy of particles obeying Fermi-Dirac statistics at absolute zero t
1. A gas occupying a volume of 725mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final the volume?
2. The volume of a gas is 5.80L, measured at 1.00 atm. What is the pressure of the as in mmHG if the volume is changed to 9.65 L? (The temperature r
A monatomic ideal gas(y=1.67) is contained within a box whose volume is 2.5 m^3. The pressure of the gas is 3.5 x 10^5 Pa. The total mass of the gas is 2.3 kg.
