The reason this happens has to do with the nature of heating effect.
When an object or substance heats up, the atoms in it which compose it start to move and vibrate more faster.
This vibration pushes them apart, causing them to take up more space.
That means that a given volume of air will have fewer atoms in it, because some of them were pushed out as it expanded.
Fewer atoms means less mass,isn't it ?
and hence less weight per volume.
Less weight per volume means less density.
I hope you understand,
Please mark me brainliest :) and best of luck for your test.
