What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature.

What is kinetic energy?

Back

Kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has.

What is the difference between solids, liquids, and gases in terms of thermal energy?

Back

In solids, particles are closely packed and vibrate in place. In liquids, particles are close but can move past each other. In gases, particles are far apart and move freely.

What is the role of heat lamps in keeping baby chickens warm?

Back

Heat lamps provide thermal energy through radiation, warming the chickens without direct contact.
