Heat and 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 the average kinetic energy of the particles in a substance.

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.

Front

What is radiation?

Back

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

Front

What happens to particles in a solid when heat is added?

Back

The particles vibrate faster and may eventually break free from their fixed positions, leading to melting.

Front

What is thermal energy?

Back

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

Front

How does heat transfer occur between an ice cube and water?

Back

Heat transfers from the warmer water to the colder ice cube, causing the ice to melt.

Front

What is the effect of increasing temperature on the thermal energy of a substance?

Back

Increasing the temperature of a substance increases its thermal energy.

Front

What is the role of insulation?

Back

Insulation reduces the transfer of heat between objects, helping to maintain temperature.
