The energy store in stretched or compressed objects

• Elastic

• Kinetic

• Chemical

• Thermal

The energy store in food and fuel

• Chemical

• Thermal

• Potential

• Calories

This quantity is a measure of the average kinetic energy of the individual particles in the object

• specific heat capacity

• temperature

• volume

• heat

What causes the transfer of thermal energy?

• temperature difference

• temperature

• radiation

• conduction

If two objects have different temperatures, energy is transferred from the warmer object to the cooler one UNTIL ...

• one reaches a temperature of zero

• they both have an equal temperature

• one runs out of energy

When energy is transferred from one particle of matter to another without the movement of the matter it is called

• conduction

• convection

• radiation

When energy is transferred by the movement of currents within a fluid it is called

• conduction

• convection

• radiation

The transfer of energy by electro-magnetic waves is called

• conduction

• convection

• radiation

What is the formula to calculate the energy (Q) required to raise the temperature (T) of a mass (m) of a substance?
