What are the differences between heat and temperature?

Solution
Heat Temperature
i) Heat is energy which produces the sensation of warmthness. i) Temperature is the physical condition that tells us the direction of flow of heat.
ii)  The flow of heat from one body to another does not depend on the amount of heat energy in the body i.e. heat can flow from a body having low heat energy to another body having high heat energy and vice versa. ii) Heat can flow only from a body at high temperature to another body at low temperature spontaneously.
iii) When heat flows from one body to another, the amount of heat energy lost by the hot body is equal to the amount of heat energy gained by the cold body. iii) Fall of the temperature of the hot body need not necessarily to be equal to rise in temperature of the cold body.
iv) Heat energy of the body can increase without increasing the temperature e.g. during phase transition the temperature of the body remains constant. iv) Temperature of the body cannot increase without increasing the heat energy of the body
