Change in State of Matter

A large piece of ice is placed on the sidewalk on a warm day. What will happen to the ice? 

• It will melt to form liquid water
• It will melt to form water vapor
• It will not change at all.
• It will freeze to form liquid water. 

How can you make liquid water become a solid?

• Add a lot of salt to the water.
• Put the water in a very cold place
• Shake the water container very fast.
• Heat the water on the stove.

Snow turns to liquid water when it

• freezes
• evaporates
• condenses
• melts.
