Difference Between Kinetic Temperature and Radiant Temperature

Kinetic Temperature: Kinetic temperature (Tkin) of an object is measured through direct contact of the object’s surface. Normally when we are referring temperature of an object, we are referring to kinetic temperature. It is called true temperature of the object. It can be measured using a thermometer. Radiant Temperature: Radiant temperature (T rad) of an …
