In order to quantify the heat transfer, q, that is associated with changing the temperature of a substance, the mass, m, and specific heat, c , of that … WebJul 29, 2024 · The transfer of heat energy is defined as heat flux, Q. By definition, this is the flow of heat energy through a defined area over a defined time. So, the units for Q are Joules (energy) divided by area (square meters) and time (seconds). Joules/(m^2∙sec). Since power is defined as energy divided by time and 1 Watt is equal to 1 Joule/second ...
