A heat pump system operates between a room at 2 7 C and an external environment at 8 C . Determine the maximum theoretical Coefficient of Performance ( COP ) .

A rigid tank whose volume is unknown is divided into two compartments by a partition. One side of the tank contains an ideal gas at 9 2 7 C and an unknown pressure. The other compartment is initially evacuated and has a volume twice the size of the compartment with the ideal gas. The partition is now removed, and the ideal gas expands to fill the
