Thermal Energy

Thermal Energy → sum of the kinetic and potential energy of all the particles in an object; thermal energy of an object increases as temperature increases

Heat → thermal energy that flows from something at a higher temperature to something at a lower temperature

Thermal Energy Transfer

Conduction → Transfer of thermal energy by collisions between particles in matter. Occurs in solids, liquids, & gases. Metals are the best conductors.

Convection → Transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place. Occurs in liquids & gases.

Radiation → Transfer of energy by electromagnetic waves. Occurs in gases only.

Multiple Choice

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

• conduction

• convection

• radiation

Multiple Choice

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

• conduction

• convection

• radiation

Multiple Choice

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
