Question

Will heating up an object increase or decrease its density?

Answer 1

Answer: It will certainly decrease in its density

Explanation: When you heat an object up, the particles will soon move away from each other and constant moving in random directions. They spread apart and that is why it becomes less dense.

Answer 2

Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density.
