Sol: Temperature is a macroscopic concept . This means that temperature is an average property of the large number of molecules which constitute a system . We can not define the temperature of a single molecule .

Is temperature a macroscopic property?

Temperature is a macroscopic parameter that is a measure of the average KE of the molecules in a system. Heat flows from the hot system (lowering its internal energy and temperature) to a cold system (raising its internal energy and temperature).

What is temperature in microscopic view?

A convenient definition of temperature is that it is a measure of the average translation kinetic energy associated with the disordered microscopic motion of atoms and molecules. The flow of heat is from a high temperature region towards a lower temperature region.
