Heat and Temperature

Front

What is the process called when energy is transferred through electromagnetic waves, such as sunlight?

Back

Radiation

Front

What are the three main methods of heat transfer?

Back

Conduction, Convection, and Radiation

Front

Which property of matter does thermal energy depend on?

Back

Mass, temperature, and phase (not shape).

Front

What is convection?

Back

The transfer of thermal energy by the movement of fluids (liquids or gases) due to differences in temperature.

Front

What does the 1st law of thermodynamics state?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is specific heat capacity?

Back

The amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius.

Front

How does the specific heat of a substance affect its temperature change?

Back

A substance with a lower specific heat will heat up faster than one with a higher specific heat when the same amount of energy is applied.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is conduction?

Back

The transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is the formula for calculating heat energy (Q)?

Back

Q = mcΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature.
