5.1 Heat & Temperature

Front

What is heat?

Back

Heat is a form of energy that is transferred between objects due to a temperature difference.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold an object is, typically measured in degrees Celsius (°C) or Fahrenheit (°F).

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, usually occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, which can travel through a vacuum.

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to pass through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through it easily, such as rubber or wood.

Front

How does thermal energy flow?

Back

Thermal energy always flows from areas of high energy (high temperature) to areas of low energy (low temperature).

Front

What happens to your feet when you step on hot sand?

Back

Your feet feel hot due to conduction, as heat is transferred from the hot sand to your skin.

Front

What is an example of convection?

Back

An example of convection is the way warm air rises and cool air sinks, creating a circulation pattern in a room.
