Adding thermal (heat) energy to matter can cause matter to change its physical state. When you remove a popsicle from the freezer, it is exposed to heat and begins to melt.

When water is brought to a boil on the stove, thermal energy causes the water to change from liquid water to a gas called water vapor. The change from liquid to gas is called evaporation.

How might an ice cube change from a solid to a liquid?

• Thermal energy causes the water to evaporate.

• Thermal energy melts the ice cube into liquid water.

• Thermal energy causes liquid water to evaporate.

• Thermal energy freezes liquid water into an ice cube.

Thermal energy is heat energy. It is transferred from warmer matter to cooler matter. It can be used to cook food, provide warmth, and produce electricity.

Which of the following does NOT describe a use of thermal energy?

• Thermal energy from the sun causes the water from the ocean to evaporate.

• Thermal energy from an iron straightens wrinkles in a shirt.

• Thermal energy from a fan cools down a classroom.

• Thermal energy on a stove boils water.
