Dec. 1-Show What You Know (spiral review)

The table above gives information about water as it changes from ice to liquid to water vapor. Does a physical or chemical change occur as this happens? Why?

• A chemical change occurs because a new substance was formed

• A physical change occurs because the water changed state, not composition.

• A physical change occurs because energy was absorbed

• A chemical change occurs because there was a change in the shape and form of the water.
