What is heat?

• The energy that is transferred from one entity to another due to temperature difference is called heat.
• Energy is transferred as a result of heat flow.
• Transfer of heat takes place by conduction, convection or radiation.

What is temperature?

• It is the degree of hotness or coldness of an object.
• It is measured through thermometers or other instruments.
• It is expressed in kelvin.

Heat flows from higher temperature to lower temperature.

Greater the heat, more is the temperature.

Hot entities have more heat than cold entities and hence temperature of hot objects are higher than temperature of cold objects.
