Thermal Energy Vocabulary Review

This type of thermal energy transfer can take place in solids, liquids, & gases when two objects are touching.

• conduction

• convection

• radiation

This type of thermal energy transfer can take place in gases only.

• conduction

• convection

• radiation

This type of thermal energy transfer can take place in fluids (liquids & gases). Rising of warmer fluid and sinking of cooler fluid forms a current.

• conduction

• convection

• radiation

• wood or plastic
• metal or rubber
• wood or rubber
• copper or steel

Conduction can only occur between two objects when –
