A piston-cylinder that has a piston initially resting on top of a set of stops initially contains 0.34 kg of helium gas at 100 kPa and 23.3°C. A pressure of 159 kPa is required to lift the piston off the stops. 2 Helium a) At what temperature will the piston begin to move? °C b) How much heat must be added before the piston starts to rise? kJ c) If the volume of the gas inside the cylinder increases by a factor of 2, what is the new temperature after this expansion process? °C d) What is the boundary work done by the gas during this expansion process? kJ e) What is the total amount of heat added during this expansion process (from its initial state to the final state after the expansion)? kJ
