Fast Facts about Heat

Fast Facts about Heat

The boiling point is the temperature at which a substance changes from a liquid to a gas.

How does the movement of the particles change as it nears the boiling point?

Fast Facts about Heat

The boiling point is the temperature at which a substance changes from a liquid to a gas.

How does the movement of the particles change as it nears the boiling point? The particle move faster and faster until they escape from the liquid.

What is energy?

Energy is the ability to cause a change.

Energy is the ability to do work. Our bodies use food to make energy so we can play and read and clean our rooms. The other types of energy we use help make our lives easier and more comfortable.

What is thermal energy?

Thermal energy is the motion of particles in matter. Thermal means heat . We feel the thermal energy of particles in matter as heat. When you add thermal energy to matter the particles move faster.

What is temperature?

Temperature is the measure of the average energy of motion of particles in matter. When the particles in the air move more slowly, they have less thermal energy.
