Heat Transfer/Specific Heat

Front

What happens to the particles of matter when the temperature increases?

Back

The particles speed up and move farther apart.

Front

What is water classified as in terms of thermal properties?

Back

Water is a thermal insulator.

Front

How do you calculate the temperature change when a material is cooled from 100ºC to 40ºC?

Back

The temperature change is -60ºC.

Front

What type of heat transfer occurs when a hot plate conducts heat to a student's finger?

Back

The hot plate conducts heat to the student's finger and radiates heat to the air.

Front

What energy transformation occurs when a match is rubbed against sandpaper and starts to burn?

Back

The chemical energy stored in the match changes to thermal and light energy.

Front

Define conduction in the context of heat transfer.

Back

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

Front

What is convection and how does it occur?

Back

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

Front

Explain radiation in terms of heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 degree Celsius.

Front

How does a thermal conductor differ from a thermal insulator?

Back

A thermal conductor allows heat to pass through easily, while a thermal insulator resists heat transfer.
