Heat and temperature 

                 WHAT IS HEAT?

Sir Benjamin Thompson and James Prescott joule performed various experiments and explained  that heat is a from  of energy. We often describe different substances as hot or cold.  Hot and cold are relative terms. It means that something is considered as hot 

When it is compared to something which is colder.

Heat is a form of energy that spontaneously moves from the systems to its surroundings or vice versa. It happens due to the movement of tiny particles that  make up solids liquids and games.  If we put warm and cool objects together Heat is transferred from warm object to the cool object until both objects have the same temperature.  This stage is known as equilibrium stage. Hotness or coldness of a body is measured in as temperature.  The hotter an object is the higher is the temperature. Temperature is mostly measured degree Celsius ( *c ) 37.
