A gas is compressed at a constant pressure of 0.800 atm from 9.00 L to 3.00 L. In the process, 400 J of energy leaves the gas by heat. Required:
a. What is the work done on the gas?
b. What is the change in its internal energy?

An ideal gas is held in a container at constant volume. initially, its temperature is 5 degrees c and its pressure is 1.2 atm. what is its pressure when its temperature is 43 degrees c? answer in units of atm
