The process in which a solid changes to a liquid is called melting.
melting point
The property that separates styrofoam balls is their buoyancy. Styrofoam balls are lightweight and have air trapped inside, making them less dense than water. This causes them to float on the surface of water, separating them from denser materials that sink.
it is simply melting process.
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.

its called melting.
A chemical reaction called acetic acid which creates the fizzing reaction.
Its a polyatomic ion called Acetate
Some glues melt styrofoam as those glues solvents are not compatable for styrofoam. You need an adhesive called PL300 or Clearco 444 to properly glue styrofoam.

Acetone's has the formula C3H6O. The elements that makeup this organic compound are hydrogen, carbon, and oxygen. Acetone also is called propanone.

Yes & No...Acetone will not "etch" styrene. Styrene is a monomeric aromatic building block which can be polymerized to long chains. This is the plastic commonly called polystyrene and is recyclable with the recycling symbol including the number 6 in the center and the letter PS below the symbol for easy identification. Acetone will not "etch this plastic compound. Many variations have been used of the basic PS including copolymers added to the mix to produce a stronger or more flexible version of the original.One company (DOW) injected tiny air pockets throughout the plastic allowing it to be manipulated in a whole new way. This new product was trademarked as Styrofoam, and it had new properties including floatation in water, insulation of heat and was much cheaper to make since the bulk of the product was air! Styrofoam, generically referred to as polystyrene foam, CAN be "etched" by acetone! This is possible because rather than affecting the polystyrene in general, the acetone acts as a solvent and allows the air to be released from the PS foam.(be sure to work in a well ventilated area, and use acetone from the hardware store rather than cosmetic grade, this is a much more pure form of acetone)
DO NOT USE STYROFOAM IN MICROWAVE !!!!!!!! Dangers include melting of styrofoam and leeching of toxic chemicals into food. Use glass dishes, stoneware or paper plates. Use only plastic containers labeled microwave safe. Additional information: Harvard Medical School has an online publication called Health Beat.
