The first law of thermodynamics states that the change AU in the internal energy of a system is given by AU = Q - W where Q is the and Wis a positive heat, and Wis the work. Both Q and W can be positive or negative numbers. Q is a positive number if number if O the system gains heat, work is done on the system. O the system loses heat, work is done by the system. O the system gains heat, work is done by the system. O the system loses heat, work is done on the system.
