1. The physical quantity of heat transfer and its unit 1-1 Temperature and heat temperature of two different objects in contact, the heat from high temperature objects to low temperature objects. The process of heat transfer is called heat transfer. The unit of temperature T is [K] (Kelvin), and Celsius temperature Q [C] is also commonly used. The relationship between T and Q is as follows. T [K] = Q [° C] + 273.15 ............ [1-1] Temperature difference ΔT [K] often occurs in heat transfer calculation and
