Structure and properties of solids, liquids and gasses

Question 1

describe a structure of a solid?

Answer 1

particles vibrate about fixed position; regular structure.

Question 2

describe a structure of a liquid?

Answer 2

particles can move around each other, but they collide often.

Question 3

describe a structure of a gas?

Answer 3

particles are more free and at random in all direction, but they collide less often than in liquid.

Question 4

what are the properties of a solid ?

Answer 4

solids are rigid, non-compressible , they have fixed shape and volume and they cannot flow. Example: computer

Question 5

what are properties of a liquid?

Answer 5

liquids are not rigid, non-compressible, they have no fixed shape but have fixed volume and can flow. Example: water at room temperature.

Question 6

what are properties of a gas?

Answer 6

Gasses are not rigid, compressible, have no fixed shape and no fixed volume and can flow. Example: Helium, liquid nitrogen.
