Why do crayons melt then harden?
Because they aren%26#039;t kept hot to keep melting. Hope I helped and have a great day!
Why do crayons melt then harden?
If you%26#039;re asking for a simple explanation of why things melt and harden when warmed and cooled:


Energy travels from the heated area (like the bottom of a pot) to the wax. When the energy hits the wax molecules, it causes them to speed up, resulting in liquid. As the heat is removed, the wax molecules begin to slow down and heat the air around them. As the molecules lose energy they slowly stop moving as much and become a solid again.

Reply:Crayons are waxed based, like candles, so they melt... like candles.
