Question

Refer to the plot of temperature versus time (figure) showing the changes in the state of ice on heating (not to scale).

  1. The region AB represents ice and water in thermal equilibrium.
  2. At B water starts boiling.
  3. At C all the water gets converted into steam.
  4. C to D represents water and steam in equilibrium at boiling point.
Short Note

Solution

a and d

Explanation:

During the process AB temperature of the system is 0°C Hence, it represents phase change that is the transformation of ice into water while the temperature remains 0°C.

BC represents a rise in the temperature of water from 0°C to 100°C (at C).

Now, water starts converting into steam which is represented by CD.
