Question

Identify the factors that determine the physical states of matter?

• A. The force of attraction between particles.
• B. The space between the particles.
• C. The kinetic energy of particles.
• D. The particles are very small.

Answer 1

Answer: (A), (B), (C)

The correct options are
A The force of attraction between particles.
B The space between the particles.
C The kinetic energy of particles.

We can see that matter around us exists in three different states– solid, liquid and gas. The force of attraction between the particles of solid is maximum and the force of attraction between the particles of gases is minimum. The force of attraction between the particles of liquid is intermediate of solid and gas. If the force of attraction between the particles of matter will be high, then particles will have larger tendency to be in solid state.
This force of attraction between the particles of matter provides the space between the particles. The space between the particles of solid is minimum and space between the particles of gases is maximum. Similarly, kinetic energy of the particles of solid is minimum and kinetic energy of particles of gases is maximum. The kinetic energy of liquid is intermediate of gas and solid. If the kinetic energy of the particles will be high, then particles will have larger tendency to be in gaseous state.
