Energy Transfer

A measurement of the average amount of kinetic energy of the particles in a sample of matter.

• Temperature

• Energy

• Potential energy

• Heat

The transfer of thermal energy between objects

• Kinetic energy

• Temperature

• Heat

• Potential energy

The diagram shows different forms of thermal energy transfer.

Which process is making the pot's handle hot?

• Conduction

• Insulation

• Convection

• Radiation

Which two options are a result of convection currents in the air on Earth?

• Storm systems

• Clouds

• Electromagnetic waves

• Tides

Which event is part of a convection current in the air?

• Cool air sinks.

• Cool air rises.

• Warm air sinks.

• Warm air swirls.

The movement of thermal energy from a warmer object to a cooler object is called:

• heat
• temperature
• motion
• momentum

Heat transfer occurs:

• in many directions
• both from warm objects to colder ones and from cold objects to warmer ones
• only from warm objects to colder ones
• only from cold objects to warmer ones

Energy that moves particles of matter is 

• temperature
• thermal energy
• heat
• friction

The temperature of a substance increases as___.

• the substance expands
• the average kinetic energy of its particles increases
• the substance's volume increases
• the substance's mass increases

The heat transfer in the image is by

• convection
• conduction
• radiation
