A) Ice is contained in a Styrofoam container and is melting, as in the FNT problem you did. The temperature of the ice is 0° C, while the temperature outside is 30° C. Does the bond energy of the ice, E Bond , change exponentially while the ice is melting? Check an answer then explain briefly. Yes: & No: & B) In DL, you filled a piece of dialysis tubing with a sucrose solution, then placed it in distilled water and watched osmosis happen. Did the concentration of water in the dialysis
