Answer 1

Answer:

A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.

Answer 2

1. Shape

Solid They have a definite shape

Liquid They do not have a definite shape

Gases They do not have a definite shape

2. Volume

Solid They have a definite volume

Liquid They do not have a definite volume

Gases They do not have a definite volume

3. Density

Solid They have high-density

Liquid Liquids have less density than solids

Gases Gases have the least density

4. The kinetic energy of particles

Solid Least

Liquid More than solids

Gases Maximum

5. Compressibility

Solid Negligible

Liquid Low

Gases High
