Thermal Physics

Question 1

Internal Energy??

Answer 1

the sum of random distribution of kinetic and potential energies of its atoms or molecules.

Question 2

First Law Of Thermodynamics??

Answer 2

increase in internal energy= energy supplied by heating+energy supplied by doing work

Question 3

specific heat capacity??

Answer 3

of the substance is the energy required per unit mass of the substance to raise the temperature by 1K.

Question 4

specific latent heat??

Answer 4

of a substance is the energy required per kg of the substance to change its state without any change in temperature.

Question 5

thermal energy??

Answer 5

energy flowing from the region of higher temperature to the region of lower temperature is thermal energy.

Question 6

thermal equilibrium??

Answer 6

when two objects, in contact with each other are at the same temperature there will be no transfer of thermal energy between them.
