Q: Do most substances increase or decrease in size when they change from a liquid to a solid?


Read this paragraph and choose the correct option from the provided answers:

This is how ice wedging works. When liquid water changes into solid ice, it increases in volume. You see this when you fill an ice cube tray with water and put it in the freezer. The ice cubes go to a higher level in the tray than the water. You also may have seen this if you put a can of soda into the freezer so that it cools down quickly. If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can. (For the record, water is very unusual. Most substances get smaller when they change from a liquid to a solid. ).

 Choices:

- increase

- stay the same

- it is unable to be measured

- decrease


A:
decrease
