Heat Flashcard 21-22

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one, like a metal spoon getting hot in hot chocolate.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a cycle.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, such as when you feel warmth from the sun.

Front

What is energy?

Back

Energy is the ability to do work or cause change. It exists in various forms, including kinetic energy, potential energy, thermal energy, and more.

Front

What is thermal energy?

Back

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

Example of conduction:

Back

Touching a hot stove and getting burned is an example of conduction.

Front

Example of convection:

Back

Boiling water in a pot is an example of convection, as the hot water rises and cooler water sinks.

Example of radiation:

Back

Getting hot from lying in the sun is an example of radiation.

Front

What happens to particles during conduction?

Back

In conduction, particles collide with each other, transferring heat energy from the hotter object to the cooler one.

Front

What happens to particles during convection?

Back

In convection, warmer particles move up while cooler particles move down, creating a circulation pattern.
