Thermal Energy

In the situation illustrated, how will heat energy move? Heat energy will be transferred from –

• the water to the hot plate by convection.
• the water to the hot plate by conduction.
• the hot plate to the water by convection.
• the hot plate to the water by conduction.

Radiation is a method of thermal energy transfer that moves -

• through empty space.
• when objects touch.
• only through solids.
• in the motion of fluids.

What two kinds of heat transfer are represented?

• stove→pot=radiation pot→egg=conduction
• stove→pot=conduction pot→egg=radiation
• stove→pot=convection pot→egg=conduction
• stove→pot=conduction pot→egg=convection

Which of the following is an example of conduction?

• Solar energy warming a room.
• Heat rising from the coils of a stove.
• Hot air drying a wet towel.
• Heat moving from a clothes iron to a shirt.

• Conduction
• Convection
• Radiation
