Question

Which of the following can transform matter from one state to another?

• A. Change in temperature
• B. Change in concentration
• C. Change in pressure
• D. None of the above.

Answer 1

Answer: (A), (C)

The correct options are
A

Change in temperature

C

Change in pressure

Particles in solids have lesser kinetic energy when compared to liquids and gases. As temperature increases, the state changes from solids to liquids and then to gases.
In solids, particles are much closer to each other, the kinetic energy and the distance between the particles increase when the state changes from solid to liquid and then to gas. With the increase in pressure and decrease in temperature, gases can be converted to liquids and then to solids. Application of pressure brings the particles closer and decrease in temperature lower down the kinetic energy and increase the interparticle forces of attraction.
