Helium gas at 105.0 kPa and 309.0K is located within a cylinder with a piston. Initially the gas occupies 0.4000 m. While a constant force, F, is applied to the end of the piston so that the pressure inside the cylinder is held constant at 105.0 kPa, 5090.0 J of heat is transferred to the helium gas. The specific enthalpy of helium gas is given by the approximate relation: (kJ/mol) = 0.02087(K) Q=5090.0J Final Conditions P2 = 105.0 kPa Initial...

Two moles of helium are initially at a temperature of 24.0 ∘C and occupy a volume of 2.50×10−2 m3 . The helium first expands at constant pressure until its volume has doubled. Then it expands adiabatically until the temperature returns to its initial value. Assume that the helium can be treated as an ideal gas. Part A What is the total heat supplied to the helium in the process? Part B What is the total change in internal energy of...
