The sun warming your skin is an example of heat transfer through 

• conduction

• convection

• radiation

• thermal electricity

As you touch a hot stove the heat transfers -

• from your hand to the stove

• from the stove to your hand

• It doesn't transfer

Which type of energy transfer involves mass movement of a fluid?

• Conduction

• Convection

• Radiation

• Insulation

In the process of conduction, heat is transferred through:

• Fluids rising and falling

• Electromagnetic waves

• Direct contact between materials

• Movement of air or liquid currents

What is the process called when heat is transferred through a solid by direct contact of its particles?

• Convection

• Conduction

• Radiation

• Insulation

Describe the transfer of heat in the example: Ice Pack on Person

• Heat is transferred from the ice pack to the person.

• Heat is transferred from the person to the ice pack

• The ice pack is getting colder. The person is getting warmer.
