Front

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What is Kinetic Energy (K.E.)?

Back

Kinetic Energy is the energy of motion. More kinetic energy means particles move faster and get hotter.

Front

What is Thermal Energy?

Back

Thermal energy is the total energy of all the particles in an object, related to temperature and heat.

Front

What is Conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Heat moves from the hotter object to the cooler one.

Front

What is Radiation?

Back

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

Front

What is Insulation?

Back

Insulation is a material that reduces the transfer of heat, keeping warmth in or cold out.

Front

What happens when particles collide?

Back

When particles hit each other, they can transfer energy between them.

Front

What type of particles are in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

What type of particles are in a liquid?

Back

In a liquid, particles are close together but can move past each other, allowing liquids to flow.
