A system consisting of an ideal gas at the constant pressure of 120 kPa gains 960 J of heat. Find the change in volume of the system if the internal energy of the gas increases by (a) 900 J or (b) 360 J.

the volume of an ideal gas is decreased from 5L to 5mL at a constant pressure of 1 atm. Calculate the work associated with this process.

A piston-cylinder assembly contains 0.7 lb of air initially at a pressure of 30 lbf/in² and a temperature of 100°F. The air is heated at constant pressure until its volume is doubled. Assume the ideal gas model with constant specific heat ratio, k = 1.4. Determine the work and heat transfer, in Btu.

A monatomic ideal gas expands adiabatically from 1.8 m³ to 4 m³. If the initial pressure is 102 kPa, calculate the energy in kJ transferred to or from the system by heat.

A diatomic ideal gas contracts at constant pressure of 159 kPa from 2.7 m³ to 1.7 m³. Calculate the change in the internal energy in kJ during the process.
