Heat & temperature

Heat is...

• a means of transferring energy between 2 bodies that are at different temperatures.

• a non-renewable source of energy

• a means of transferring energy between 3 bodies that are at the same temperature.

• a means of transferring electricity between 2 bodies that are cold.

We can use a thermometer to measure the heat of a body

• True

• False

When ahot body and a cold body are in contact ...

• the heat is transferred from the cold body to the hot body.

• the heat is transferred from the hot body to the cold body.

• the heat is not transferred.

When 2 bodies reach the same temperature, we say in scientific terms they have reached...

• thermal equilibrium.

• the same temperature.

• the same heat.

• the energetic equilibrium.

Heat can change matter in...

• size and state.

• state.

• size.

• flavour.

Thermal contraction occurs...

• when an object shrinks.

• when an object expands.

• when matter change from solid to liquid state

• when matter change from gas to liquid state

Mark the 3 states you can find matter

• Liquid

• Solid

• Gas

• Dust

Process of changing from a solid substance to a liquid:

• Evaporation

• Melting

• Solidification

• Condensation
