1. Air in a cylinder with a volume of 500 cm3 is compressed by a piston to a volume of 150 cm3. If the initial air pressure is 5 x 104 Pa (N/m2), what is the pressure in the cylinder after compression? (Assume that this is a slow process, and that T remains constant.) 8. The sample of gas in Question 2 is contained in a rigid closed container. If the pressure of the gas is 1013 mb at 20°C, what...

A gas is compressed from an initial volume of 5.40 L to a final volume of 1.24 L by an external pressure of 1.00 atm. During the compression the gas releases 120 J of heat. What is the change in internal energy of the gas?
4-10 A gas is compressed from an initial volume of 0.42 m^3 to a final volume...
4-10 A gas is compressed from an initial volume of 0.42 m^3 to a final volume of 0.12 mm. During the quasi-equilibrium process, the pressure changes with volume according to the relation P = aV + b, where a = -1200 kPa/m^3 and b = 600 kPa. Calculate the work done during this process (a) by plotting the process on a P-V diagram and finding the area under the process curve and (b) by performing the necessary integrations.

Q-1 Air at 1 atm and 20 0C occupies an initial volume of 1000 cm3 in a cylinder. The air is confined by a piston which has a constant restraining force so that the gas pressure always remains constant. Heat is added to the air until its temperature reaches 260 0C. Calculate (a) the heat added (b) the work done by the gas, (c) the change in internal energy of the gas. Q-2 An ideal gas is contained in a...
