Heat Transfer

When two objects with different temperatures try to reach the same temperature, this is called...

• thermal transferrance

• thermal equilibrium

• temperature matching

• twin temperatures

Which is the best example of the transfer of heat by radiation?

• water boiling

• ice melting

• a hot air balloon rising

• a lightbulb glowing

A pot is heated on the stove. Which process causes the metal handle of the pot to also become hot?

• combustion

• convection

• radiation

• conduction

People sitting around a campfire are able to feel the heat from the fire. How are the people able to feel the heat from the fire without touching the fire?

• The heat from the fire travels through the ground and heats the ground around the people.

• The heat from the fire is conducted through air molecules to the people.

• The heat from the fire rises in the air and then settles around the people.

• The heat from the fire radiates from the fire to the people.

Stirring a hot tea causes a metal spoon to get warm. Which statement best explains why the spoon gets warm?
