You must have studied that, when ice is heated, it changes into
water and when water is further heated it boils and changes into
steam. Similarly, change of state occurs to matter in all states.
Complete the flow chart given below.

................ cooled

Which form of energy is responsible for the change of state here?
Observe the figure that depicts the movement of particles
in solid, liquid and gas
(Figure 4.5).
What are the changes that
happen to the following
properties when heat is
absorbed?
