What is conduction?

• The transfer of heat through a fluid medium

• The transfer of heat through direct contact (touch)

• The transfer of heat through electromagnetic waves

• The transfer of heat through a vacuum

What happens when you hold an ice cube in your hand according to the example of conduction?

• The ice cube absorbs heat from the hand and freezes further

• The ice cube remains unchanged in temperature and state

• The heat energy passes from the ice (cooler object) to your hand (warmer object)

• The heat energy passes from your hand (warmer object) to the ice (cooler object), causing the ice to melt
