Thermal Energy Transfer

Heat transfer always goes from-

• Cold to Hot
• Hot to Cold
• Heat doesn't transfer
• Freezing to Cold

Conduction is heat transfer by -

• Touch
• Circles
• Waves

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

What happens to particles as they cool down?

• They slow down
• Nothing
• They don't move
• They speed up

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

Hot objects begin to cool as-

• cooler air is transferred to the hot object.
• thermal energy in the object is transferred to the surrounding air.
• atoms in the object react with the oxygen in the air.
• thermal energy in the object cancels out energy in the air

Radiation is the transfer of energy from one material to another by

• objects touching

• electromagnetic waves

• particles from one material to another

• waves of the ocean

Convection is the transfer of thermal energy by

• the movement of particles from one part of a material to another

• the suns rays

• a hot spoon in a cup of soup

• temperatures that are the same

Conduction is the transfer of thermal energy between materials by

• electromagnetic waves

• waves from water or sun

• the collision of particles

• movement of rays

Thermal equilibrium is

• when one solid is hot and one solid is cold

• when temperatures of materials in contact are the same

• when one liquid freezes and another turns hot

• a toaster toasting bread
