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?

Back

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

Explain radiation as a method of heat transfer.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, and does not require a medium.

Front

How does temperature relate to thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, which is directly related to its thermal energy.

What happens to thermal energy when ice melts?

Back

When ice melts, thermal energy is absorbed from the surroundings, increasing the kinetic energy of the water molecules.

Give an example of conduction in everyday life.

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of boiling water.

Front

What is the role of density in convection currents?

Back

Density differences in fluids create convection currents, as warmer, less dense fluid rises while cooler, denser fluid sinks.
