As we increase the temperature of any state, particles expands:
i. If we apply increasingly temperature on solid, it will change into liquid.
ii. If we apply increasingly temperature on liquid, it will change into gas.
iii. As we decrease the temperature of any state, the particles come closer:
iv. If we apply reducing temperature on gas, it will change into liquid.
v. If we apply increasingly temperature on liquid, it will change into solid.
