Energy transfer

Front

What determines the temperature of an object?

Back

The speed of the atoms.

Front

In which direction does energy (heat) move between objects?

Back

From a hotter object to a colder object.

Front

What can you say about the speed of atoms in a cold object?

Back

They are moving slowly.

Front

What type of energy transfer occurs when an ice cube is dropped into warm water?

Back

Conduction, from water to ice.

Front

What is the energy transfer called when hot air rises and cold air sinks?

Back

Convection.

Front

Define conduction in the context of energy transfer.

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation in terms of energy transfer?

Back

Radiation is the transfer of energy through electromagnetic waves.

Front

How does temperature relate to the speed of atoms?

Back

Higher temperatures mean atoms move faster, while lower temperatures mean atoms move slower.

Front

What happens to the energy of a hot object when it comes into contact with a cold object?

Back

Energy transfers from the hot object to the cold object.
