Energy can cross the boundaries of a closed system in the form of heat or work. It is only a closed system if we include both the gas and the reservoir. As a hot air balloon cools down it is compressed by the air around it. The First Law of Thermodynamics Work and heat are two ways of transfering energy between a system and the environment, causing the system’s energy to change. However, the gas itself is not a closed system.
