Question

EXERCISE
1. Define heat energy (a) on conventional basis (b) on the basis of kinetic theory of matter,
? Define temnerature (a) on conventional basis (b) on the basis of kinetic theory of matter,​

Answer 1

Answer:

1-A- Heat energy : It is a form of energy which causes in us the sensation of hotness or coldness.

B - Heat energy : On the basis of kinetic theory of matter, heat energy is defined as the sum total of kinetic and potential energies of all the molecules of a given substance.

2-A- IDK

B-temperature of a body is determined by the average kinetic energy of its particles and that an inflow of heat increases this energy.

Answer 2

Heat is a form of energy.

In Thermodynamic, The change in internal energy of a closed system is equal to the amount of heat applied minus the amount of work done by the system.

And is represented by : ∆ U = Q - W
