Question

Which of the following phenomenon 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.
As we know, in solids, particles are much closer to each other and the distance between the particles increases as we move towards the gaseous state. So, with the increase in pressure, gases can be converted to liquids and then to solids.
