Question

(ii) Melting is not a _________ change.
a) physical change b) exothermic change
c) endothermic change d) reversible change

Answer 1

Answer:

b) exothermic change

Explanation:

Melting is a 'physical change' as it can be reversed and the composition of the substance remains the same.

Melting is a 'endothermic change' as it absorbs heat and makes i's surrounding cooler.

Melting is a 'reversible change' as I can be frozen back to it solid form. Example: After melting ice, ic=t can be put in freezer for sometime to make it solid again.

But Melting is not a 'exothermic change' as it doesn't releases heat.
