Question

What determines the state of matter in a material?

• A. Motion and strength of attraction between particles
• B. Solid, liquid or gas
• C. Strength of attraction between solid particles and liquids
• D. The hardeness or softness of a material

Answer 1

The correct option is A Motion and strength of attraction between particles

The three states of matter include solids, liquids and gases. A material is assumed to be in liquid state when the molecules are not closely packed and have intermolecular space between them. In case of gases the molecules are at a greater distance from one another, they are free to move in all directions and intermolecular force of attraction is very less. So the state of matter in a material depends on the motion and strength of attraction between particles.
