Heat Transfer

Front

How does heat move?

Back

Heat moves from a warmer object to a cooler object.

Front

How is energy from the Sun transferred?

Back

Energy from the Sun is transferred by radiation.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is; specifically, it measures the average kinetic energy of the particles in an object.

Front

What happens to molecules when they move quickly?

Back

The quicker a molecule moves, the warmer it is.

Front

What is conduction?

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?

Back

Radiation is the transfer of energy through electromagnetic waves.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which all molecular motion stops, equivalent to -273.15°C or 0 K.

Front

What is specific heat?

Back

Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is an example of conduction?

Back

An example of conduction is when the handle of a metal spoon warms up when placed in a hot bowl of soup.
