A gas is contained in a cylinder at a pressure of 1 atm and a temperature of 25°C. The cylinder is fitted with a piston that can be moved to change the volume. The gas is allowed to expand irreversibly to a final pressure of 0.5 atm, and the temperature is kept constant. Calculate the work done by the system, and determine if the process is endothermic or exothermic.
