Get PriceHeat balance. An application of the first law of thermodynamics to a process in which any work terms are negligible. For a closed system, one that always consists of the same material, the first law is Q + W = ΔE, where Q is the heat supplied to the system, W is the work done on the system, and ΔE is the increase in energy of the material forming the system.
