Assertion (A): During melting of ice, the temperature of the system does not change after the melting point is reached, till all the ice melts.
Reason (R): When ice is heated, the heat gets used up in changing the state by overcoming the forces of attraction between the particles.

Solution

The correct option is C Both A and R are true and R is the correct explanation of A
During melting of ice, the temperature of the system does not change after the melting point is reached, till all the ice melts.
This is because when ice is heated, the heat gets used up in changing the state by overcoming the forces of attraction between the particles.
As this heat energy is absorbed by ice without showing any rise in temperature, it is considered that it gets hidden into the contents of the beaker and is known as the latent heat of fusion.

Therefore, both A and R are true and R is the correct explanation of A.

(a) increases very slowly
(b) does not increase at all
(c) first remains constant and then increases

Read the given paragraph on the process of melting. Identify the incorrect parts of the process.

Melting or fusion is a chemical process that involves the change of state from gaseous to liquid state on the liberation of heat. During the process of melting, there is a sharp change in the temperature until the process is complete. The temperature at which solid melts or changes into its gaseous state is known as the freezing point. During the melting of a solid, the heat released by the body does not raise its temperature. For example, the melting point of ice is 100°C, so the temperature of ice remains steady until all the ice melts.

Q. Which of the following statement is incorrect-a)The melting point of ice is 0°c b) Cooling is produced during melting c)Temperature changes slowly on heating ice d)On melting temperature stays at 0°c for water.
