TE_ Vocab/Concepts Flashcard "F" (Final)

Front

What is energy transfer?

Back

The process of energy moving from one system or object to another.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the difference between total kinetic energy and average kinetic energy?

Back

Total kinetic energy is the sum of the kinetic energies of all particles in a system, while average kinetic energy is the total kinetic energy divided by the number of particles.

Front

What is convection?

Back

A type of heat transfer that occurs in fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is conduction?

Back

The transfer of heat through a solid material without the movement of the material itself.

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What happens to the air temperature when soup cools down?

Back

The air temperature remains relatively unchanged because the air has a higher total kinetic energy than the cooling soup.

Front

What is thermal equilibrium?

Back

A state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

How does warm air rise?

Back

Warm air is less dense than cooler air, causing it to rise due to buoyancy.

Front

What is an example of conduction in everyday life?

Back

A metal spoon getting hot when placed in a bowl of hot soup.
