Conduction and Insulation

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials, where faster-moving particles transfer energy to slower-moving particles.

Front

What is insulation?

Back

Insulation is a material or method that reduces the transfer of heat, sound, or electricity, helping to maintain temperature and conserve energy.

Front

What happens to the kinetic energy of particles when a substance contracts?

Back

The kinetic energy of the particles decreases, causing them to move closer together and the substance to shrink.

Front

What is a good example of an insulator?

Back

Wood is a good example of an insulator, as it does not conduct heat well.

Front

What is the direction of thermal energy transfer?

Back

Thermal energy transfers from the warmer object to the cooler object.

Front

How does a hand warmer work to warm hands?

Back

A hand warmer transfers heat to the hands by conduction, increasing the kinetic energy of the particles in the hands.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, microwaves, and X-rays.

Front

What is the role of thermal energy in heating?

Back

Thermal energy is the energy that comes from the temperature of matter, and it is responsible for heating substances when transferred.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids (liquids or gases).

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.
