Thermal Energy Test

Convection is heat transfer by -

• Touch an object

• The heating and cooling of a fluid

• Electromagnetic Waves

• Nuclear fusion

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation 

The heat from a hot burner to a pot is transferred by ______.

• convection
• insulation
• radiation
• conduction

The sun warming your skin is an example of heat transfer through 

• conduction
• convection
• radiation
• thermal electricity

Conduction can only occur between two objects when –

• one object is less dense than the other.

• both objects are in physical contact with each other.

• one of the objects is made of a metal.

• both objects are exactly the same temperature.

Radiation is a method of thermal energy transfer that moves -

• through empty space.

• when objects touch.

• only through solids.

• in the motion of fluids.

As the thermal energy of a substance increases, its particles spread out and the substance expands.

• True
