What type of process occurs when solidified wax is converted to liquid wax on heating?
a endothermic
b exothermic
c decomposition
d reversible
e disintegration

Option (A) is the correct answer.

Explanation:

When we heat solidified wax then intermolecular boding between the molecules of wax decreases and the molecules will start to move rapidly from one place to another.

As a result, solid wax will change into liquid wax. This means that solidified wax molecules absorbed heat due to which intermolecular bondng between then weakened. Therefore, reaction is endothermic in nature.

Whereas when reactants have more energy than products in a chemical reaction then heat is released and the reaction is known as exothermic reaction.

In a decomposition reaction, a compound or molecule breaks to form two or more different substances.

For example,

And a in a reversible reaction, rate of forward reaction equals the rate of backward reaction.

On the other hand, disintegration is a nuclear decay reaction in which energy is released.

Thus, we can conclude that process which occurs when solidified wax is converted to liquid wax on heating is endothermic process.
