In an isochoric process, the volume of the gas remains constant, and no work is done by or on the gas. Therefore, any change in the internal energy of the gas is due entirely to heat exchange. If the internal energy decreases by 50 J, it means that the gas has released 50 J of heat to its surroundings. Hence, the heat exchanged with the gas is -50 J, indicating heat is lost by the gas.
