Answer:What is Matter?
We know that matter is defined as anything which has a mass and occupies some space. Matter exists in 4 forms which are solid, liquid, gas and plasma.
What is Heat?
Heat is a form of energy. It derives its origins at the molecular scale. Molecules of a substance vibrate at their positions either fixed or not when energy is supplied to them. As they vibrate they transfer their energy to the surrounding molecules causing them to vibrate as well.
This kinetic energy builds up on a macro level as more and more energy is supplied to these molecules of the substance. As a result, when this energy reaches a threshold ( eg. Melting point, Boiling point) do the molecules or atoms free themselves from interatomic forces of attraction and conversion of a state i.e. phase change takes place.
Heat energy of a body can also be defined as a form of energy that can be transferred from one body to the other or within the body itself with a temperature difference and can be generated by a body at the expense of other forms of energy. The SI unit of heat energy is Joule abbreviated as ‘J’. In CGS system, however, heat is measured in ‘Calorie’ (Cal.) where 1 Calorie = 4.186 J

Answer:
Conduction heat transfer is the transfer of heat by means of molecular excitement within a material without bulk motion of the matter. Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during their random motion.
