Imagine that you are a water molecule in an ice cube. describe what happens to you as the ice cube is heated up to a temperature of 100c.

First you would melt because the melting point for ice is 0c. Then you would become warmer and warmer as the temperature rises. Lastly once the temperature reaches 100c you'll begin to evaporate as the boiling point for water is 100c.
