Can Matter Change its State
Change of state of matter
- A substance may exist in any of the three states of matter (i.e. solid, liquid or gas) depending upon the conditions of temperature and pressure.
- By changing the conditions of temperature and pressure, a substance can be made to exist as solid, liquid or a gas.
- A solid on heating usually changes into a liquid which on further heating changes into gas. Similarly, a gas on cooling condenses into a liquid which on further cooling changes into a solid.

The most familiar and common example is water. It exists in all the three states:
- Solid : ice
- Liquid : water and
- Gas : water vapour
Ice is a solid state and may be melted to form water (Liquid) which on further heating changes into steam (gas). These changes can also be reversed on cooling.
