Question: A frictionless pistoncylinder device and a rigid tank initially contain 12 kg of an ideal gas each at the same temperature, pressure, and volume. It

A frictionless piston–cylinder device and a rigid tank initially contain 12 kg of an ideal gas each at the same temperature, pressure, and volume. It is desired to raise the temperatures of both systems by 15°C. Determine the amount of extra heat that must be supplied to the gas in the cylinder which is maintained at constant pressure to achieve this result. Assume the molar mass of the gas is 25.
