A gas in a cylinder expands from a volume of 0.110 m² to 0.320 m³. Heat flows into the gas just rapidly enough to keep the pressure constant at 1.65 x 105 Pa during the expansion. The total heat added is 1.15× 105 J. (a) Find the work done by the gas.

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 has a constant pressure of 3000Pa. It is isobarically expanded from 0.75m^3 to 1.25m^3. During the process, 100J of thermal energy is added through heat.   a) What is the work done on the gas?          b) What is the change in internal energy of the gas?

An ideal gas initially at 305 K undergoes an isobaric expansion at 2.50 kPa. The volume increases from 1.00 m3 to 3.00 m3 and 10.8 kJ is transferred to the gas by heat. (a) What is the change in internal energy of the gas? kJ(b) What is the final temperature of the gas? K

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. (a) Calculate the work done by the gas. J(b) If the internal energy of the gas decreases by 7.50 J, find the amount of energy removed from the system by heat during the compression. J

A sealed cylinder has a piston and contains 8.90×103 cm3 of an ideal gas at a pressure of 7.50 atm. Heat is slowly introduced, and the gas isothermally expands to 1.70×104 cm3. How much work ? does the gas do on the piston?

find the work done by the gas during the following stages. (a) A gas is expanded from a volume of 1.0 L to 3.5 L at a constant pressure of 4.5 atm. J(b) The gas is then cooled at constant volume until the pressure falls to 1.0 atm. J(c) The gas is then compressed at a constant pressure of 1.0 atm from a volume of 3.5 L to 1.0 L. (Note: Be careful of signs.) J(d) The gas is heated until its pressure increases from 1.0 atm to 4.5 atm at a constant volume. J(e) Find the net work done during the complete cycle. J
