A cylinder contains 0.0100 mol of helium at T = 27.0°C. (a) How much heat is needed to raise the temperature to 67.0°C while keeping the volume constant? Draw a pV -diagram for this proccss. (b) If instead the pressure of the helium is kept constant, how much heat is needed to raise the temperature from 27.0°C to 67.0°C? Draw a pV -diagram for this process. (c) What accounts for the difference between your answers to parts (a) and (b)? In which case is more heat required? What becomes of the additional heat? (d) If the gas is ideal, what is the change in its internal energy in part (a)? In part (b)? How do the two answers compare? Why?

An airtight container with the piston at 696(kPa) pressure and 269(K) temperature. When 105 kJ heat is transferred, the piston moves up and the volume changes from 0.014 to 0.056 m°. Assuming ideal gas behavior, calculate a) the change in internal energy, b) the final temperature, and c) the heat capacity.

0.3kg of nitrogen gas at 100 kPa and 40°C is contained in a cylinder.The piston is moved compressing nitrogen until the pressure becomes 2MPa and temperature becomes 160°C. The work done during the process is 60kJ. Calculate the heat transferred from the nitrogen to the surroundings. Take c, for nitrogen = 0.75 kJ/kg K.
