When you add heat to an object you increase the kinetic energy of the objects molecules which increase its what?

Answer 1

Heat is a form of energy which when added to a body increases its internal energy and is responsible for the change in thermal condition of the body. The addition of heat generally increases the temperature of the body. Hence temperature is the quantity which gives us the degree of disordered molecular kinetic energy and also provides an indication of the internal energy flow. When two bodies are in contact, internal energy flows from the body at higher temperature to the one at lower temperature irrespective of the internal energy content of each body.

Temperature of a body is that physical quantity which determines the degree of hotness or coldness of the body and the direction of heat flow.

Important differences between heat and temperature :-

(a) Heat is a form of energy and has the capacity of doing work. Temperature determines the degree of hotness or coldness of the body.

(b) Heat is the cause while temperature is the effect.

(c) When heat is supplied to a body without changing its state, the temperature of the body increases and rise in temperature is directly proportional to the quantity of heat supplied.

(d) Equality of temperature does not imply that heat content of both the bodies are the same.

(e) The direction of flow of heat depends only on its temperature but not on its heat content.
