A gas undergoes two processes. In the first, the volume remains constant at 0.170 m³ and the pressure increases from 2.00x105 Pa to 4.50x105 Pa. The second process is a compression to a volume of 0.130 m³ at a constant pressure of 4.50x105 Pa. Part A Find the total work done by the gas during both processes. Express your answer in joules. 195| ΑΣΦ W = ?

A cylinder contains 0.250 mol of carbon dioxide (CO₂) gas at a temperature of 27.0°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1.00 atm on the gas. The gas is heated until its temperature increases to 127.0°C. Assume that the CO₂ may be treated as an ideal gas. Part A How much work is done by the gas in this process? Express your answer in joules. — ΑΣΦ W = Submit Part B On what is this work done? The work is done on the piston. The work is done on the cylinder.

A large cylindrical tank contains 0.750 m³ of nitrogen gas at 22.0°C and 6.50x103 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. Part A What will be the pressure if the volume is decreased to 0.530 m³ and the temperature is increased to 165°C?
