Question

What happens to water if it is heated and Explain the phenomenon of change of state of water.

Solution

 Water on heating changes into steam at 100°C

Phenomenon of change of state of water:
Water is a liquid under ordinary conditions but, when it is kept in a deep freezer, it changes into ice at 0°C and when ice is kept at room temperature again changes back into liquid water.
Similarly, water on heating change into steam at 100°C, which on cooling changes back into liquid water. But there is no change in the chemical composition of water. When its state changes from liquid to solid or liquid to gaseous state.
 

  Is there an error in this question or solution?
