Heat and Temperature

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between substances due to a temperature difference, while temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What happens to the temperature of a substance when it gains heat?

Back

The temperature of the substance increases as it gains heat.

Front

What happens to the temperature of a substance when it loses heat?

Back

The temperature of the substance decreases as it loses heat.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in a substance.

Front

How does the mass of a substance affect its thermal energy?

Back

The thermal energy of a substance increases with its mass, assuming the temperature remains constant.

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) 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 infrared radiation.

Front

What is the boiling point of water?

Back

The boiling point of water is 100 °C (212 °F) at standard atmospheric pressure.

Front

What is the freezing point of water?

Back

The freezing point of water is 0 °C (32 °F) at standard atmospheric pressure.
