Question

which do you think is denser? less dense? can you tell why​

Answer 1

Explanation:

Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float.

Hot air pushes out on the air around it, and thus becomes less dense. Less dense air rises because the denser, cooler air sinks because it is heavier and gravity pulls on it more strongly.
