Answer 5

The amount of heat required to raise the temperature of 1 kg of a substance by 1 K

Question 6

Latent heat

Answer 6

The amount of heat required to change state of a body without a change in temperature

Question 7

Specific latent heat of Fusion

Answer 7

The amount of heat necessary to change 1 kg of a substance from a solid into a liquid without a change in temperature

Question 8

Specific latent heat of vaporization

Answer 8

The amount of heat required to change 1 kg of the substance from a liquid to a gas without a change in temperature

Question 9

Conduction

Answer 9

The movement of heat true is substance by transferring kinetic energy between adjacent particles with the no overall movement of the substance

Question 10

Convection

Answer 10

The transfer of heat true fluid by using circulating currents of fluid

Question 11
