Front

What type of heat transfer is demonstrated when baby chickens are kept warm from heat lamps?

Back

Radiation.

Front

What is the transfer of energy by touching called?

Back

Conduction.

Front

What do molecules in a liquid look like?

Back

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

Front

What do molecules in a solid look like?

Back

Molecules in a solid are tightly packed and vibrate in place, maintaining a fixed shape.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through fluid movement.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the sun.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, depending on the mass and speed of an object.
