Question

Does Polystyrene (PS) float in heated water? For example, does Styrofoam?

Answer 1

Answer 2

Also, would it deform?

Answer 3

density is determined by mass/volume. The density of water will not change until a phase change (water-->ice).

Answer 4

how about the deforming?

Answer 5

Density does change with temperature as intermolecular bonds weaken or strengthen with the addition/removal of heat. I don't think I have ever seen Polystyrene sink in water.

Answer 6

If you put a foam cup in boiling water in may definitely deform though.

Answer 7

Thank you.
