An ideal gas at 24.8°C and a pressure 1.60 105 Pa is in a container having a volume of 1.00 L.
(a) Determine the number of moles of gas in the container.
mol
(b) The gas pushes against a piston, expanding to twice its original volume, while the pressure falls to atmospheric pressure. Find the final temperature.
K
Suppose the temperature of 4.72 L of ideal gas drops from 351 K to 275 K. (a) If the volume remains constant and the initial pressure is atmospheric pressure, find the final pressure.
Pa
(b) Find the number of moles of gas.
