A gas is enclosed in a container fitted with a piston of cross-sectional area 0.150 m. The pressure of the gas is maintained at 6,200 Pa as the piston moves inward 21.5 cm. (a) Calculate the work done by the gas. (b) If the internal energy of the gas decreases by 8.90 J, find the amount of energy removed from the system by heat during the compression.

A gas is compressed at a constant pressure of 0.800 atm from 11.00 L to 1.00 L. In the process, 390 J of energy leaves the gas by heat. (a) What is the work done on the gas? (b) What is the change in its internal energy?

An ideal gas undergoes an isobaric process at a pressure of 200 kPa. The volume of the gas, which contains 35 mol of particles, expands from 0.65m3 to a final volume of 1.4m3. (a) How much work is done by/on the gas during this process? (b) What are the initial and final temperatures of the gas? (c) By how much does the internal energy of the gas change? (d) How much heat was gained/lost by the gas?

A gas is enclosed in a container fitted with a piston of cross-sectional area 0.150 m2. The pressure of the gas is maintained at 7,200 Pa as the piston moves inward 23.5 cm.

An ideal gas is compressed to half its original volume at constant temperature. (a) If 1000 J of energy is removed during the compression, how much work is done on the gas? (b) What is the change in the internal energy of the gas during the compression?

Sketch a PV diagram and find the work done by the gas during the following stages. (a) A gas is expanded from a volume of 1.0 L to 5.5 L at a constant pressure of 5.5 atm. (J) (b) The gas is then cooled at constant volume until the pressure falls to 1.5 atm. (J) (c) The gas is then compressed at a constant pressure of 1.5 atm from a volume of 5.5 L to 1.0 L. (Note: Be careful of signs.) (J) (d) The gas is heated until its pressure increases from 1.5 atm to 5.5 atm at a constant volume. (J) (e) Find the net work done during the complete cycle. (J)
