Density..?

Question

can ice be more dense than water is a glass? because the ice floats in the water, and the less dense materials float. but, ice and water are the same compound, just in different phases.

thanks!

Answer 1

No, if ice were more dense than water, it would sink. It floats.

Air, any gas,  expands with increase in temperature, which lowers its density.  Although density is not thought of as a parameter you would measure in a gas.
