ISQ tuletatud suurus
form of energy related to chaotic microscopic behaviour of a system, given by the difference between the increase of the total energy of a closed system and the work done on the system, during a process of energy transfer
difference between the increase of the total energy of a physical system and the work done on the system, provided that matter and electromagnetic energy do not cross the boundary of the system
The amount of heat power or the quantity of heat is the amount of thermal energy transferred into or out of an object, calculated with the formula Q = m⋅c⋅ΔT.
Unit (Btu) was the heat unit in the English system, and was defined as the quantity of heat needed to raise the temperature of a pound of water (about a pint).
