Thermal Physics

Question 1

Conduction

Answer 1

The transfer of heat through particles only

Question 2

Radiation

Answer 2

The transfer of heat through electromagnetic waves

Question 3

Convection

Answer 3

The transfer of heat through fluids

Question 4

Zeroth Law of Thermal Equilibrium

Answer 4

If two systems are in thermal equilibrium with a third system, then they are also in thermal equilibrium with each other

Question 5

Internal Energy

Answer 5

the sum of the randomly distributed kinetic energy and potential energy of the atoms or molecules in a substance

Question 6

Specific Heat Capacity

Answer 6

the amount of energy required to raise the temperature of 1kg by 1K

Question 7

Specific Latent Heat of Vapourisation

Answer 7

amount of energy required to convert 1kg of liquid to vapour at its boiling point at constant temperature

Question 8

Specific Latent Heat of Fusion

Answer 8

amount of energy required to convert 1kg of solid to liquid at its melting point at constant temperature

Question 9

Thermal Equilibrium

Answer 9

If a hot body and a cool body form a connected system, then energy will be transferred to equalise temperatures (restore thermal equilibrium)
