A student placed an ice cube on a table and observed it for five minutes. He noticed that the ice cube seemed to get smaller and was now surrounded by a small puddle of water. Explain what happened to the ice cube. Be sure to tell what caused the ice cube to change and how the puddle of water formed. When will the temperature of the ice cube stabilize?

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
