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.
