Question

when wax is heated, it turns into a liquid. how are the wax molecules affected by this change of state?

Answer 1

Wax molecules have most of their weak van der waals interactions and other hydrophobic interactions decrease and thus most of them are broken between these lipid substances, allowing for the increased molecular movement of these substances. As there are fewer interactions between similar compounds.

Answer 2

Step-by-step explanation:

Wax is a solid, so it's molecules will be held closer to each other by strong intermolecular forces of attraction.

As a result, when cooled down then wax obtains a define shape and volume.

On the other hand, when wax is heated then its molecules gain kinetic energy due to which there occurs more number of collisions between its particles. As a result, its molecules will move away from each other.

This will lead to change in state of wax from solid to liquid.
