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.
