Question

Marty was walking home and stepped in a puddle. When he got to his house he placed his wet sneakers outside the door. The next morning when he picked up his sneakers they were stiff and icy. Why did this happen?

Answer 1

This occurred because it got colder at night, therefore making his shoes freeze solid, and become stiff.

Step-by-step explanation:

When a cell or molecule becomes filled with water and frozen, it expands, and holds its position until melted.
