Thermal Physics Quiz

What happens to the molecules in a solid when it is heated?

• They vibrate more but stay in place.

• They move around freely.

• They become less dense.

• They escape into the air.

What is evaporation?

• The escape of molecules with higher energy from the surfaces of liquids.

• The process of a liquid turning into a gas.

• The cooling of a liquid.

• The freezing of a liquid.

What is the specific heat capacity?

• The amount of energy required to raise the temperature of 1kg of a substance by 1°C.

• The energy needed to change the state of a substance.

• The energy required to melt a solid.

• The energy needed to boil a liquid.

What occurs during melting?

• Energy is put into a body without a change in temperature.

• The temperature of the solid increases.

• The solid becomes a gas.

• The solid becomes a liquid.

What is conduction?
