temperature is 100°C. Write the energy balance for each of the two stages of the process, and in each case solve for the unknown energy term. In solving the problem, consider the gas to be the system, neglect the change in potential energy of the gas as the piston moves, and assume ideal gas behavior. Express all energies in joules.

Question
Fit to width Example: A gas is contained in a cylinder fitted with a movable piston. The initial gas temperature is 25°C. The cylinder is placed in boiling water with the piston held in a fixed position. Heat in the amount of 2.00 kcal is transferred to the gas, which equilibrates at 100°C and a higher pressure. The piston is then released, and the gas does 100 J of work in moving the piston to its new equilibrium position. The final gas temperature is 100°C. Write the energy balance for each of the two stages of the process, and in each case solve for the unknown energy term. In solving the problem, consider the gas to be the system, neglect the change in potential energy of the gas as the piston moves, and assume ideal gas behavior. Express all energies in joules.
