Explan why a piece of expanded polystyrene feels much lighter than an equal volume of lead.
(should be related to density)

Density of expanded polystyrene is lesser than the lead ....what this really means is that it has less mass (density=mass/volume) for the same volume.

I hope it helps!

It feels lighter because it has has less mass. And it has less mass because expanded polystyrene is nowhere near as dense than lead.

It has a lot of air in it. That's why it makes such a great insulator.
