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

When solidified wax is heated and converted back to liquid wax, it undergoes an endothermic process, where heat is absorbed to break the bonds in the solid structure. This is also classified as a reversible process because when the temperature decreases, the liquid wax can solidify back into its original form.

This delightful transformation is what makes candles unique! As you light a candle, the heat allows the solid wax to melt into a liquid, beautifully illuminating your space. And just like that, when the candle burns down, the wax cools and returns to its solid state, ready to be reused in another charming creation.
