Over winter break, Karter's teacher asked the class to find an example of a property of water, take a picture, and write about it. Karter and his family visited their lake house and Karter noticed the lake had froze over. What property is Karter observing?

• Ice is less dense than water.

• Surface tension allows the ice to freeze.

• Capillarity action allowed the ice to travel to the surface of the lake.

• High heat capacity allowed the ice to form on the surface of the lake.
