Answer:
Gas- 1) Compressible 2) Particles
Liquid- 1) Particles
Solid- 1) Shape and volume 2) Not 3) Cannot flow past each other
Step-by-step explanation:
In a gas, the particles are spread far apart from each other. The particles are not attached to each other. This means that they can be compressed because they have so much free space between molecules. Additionally, since they are not attached, they bounce around freely and quickly.
The particles in liquid also have independent movements. However, unlike in gas, the particles do stay together. So, there is fluid movement but it is not as random or fast as gas.
Solids are rigid shapes where the particles only vibrate. They cannot be separated from each other. The shape and volume are definite. Since there is no free space between the particles they are not compressible. Additionally, the particles cannot flow past each other.
