2.
What is ice?
Correct Answer
A. Soild
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed. In this case, ice has a definite shape and volume. So it is a solid.
3.

4.
Which states of matter can be compressed?
Correct Answer
C. Gas
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed.
5.
Which group of substances fit the description of "they have definite volume"?
Correct Answer
A. Spoon, plate, honey
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed.In this case, only examples of solid and liquid have definite volume.
6.
