Acertain amount of water of heat capacity c is at a temperature of 0°c. it is placed in contact with a heat bath at 100° c and two come into thermal equilibrium 1. what is the entropy change of the universe? 2. the process is now divided into two stages: first the water is placed in contact with a heat bath at 50° c and comes into thermal equilibrium; then it is placed in contact with the heat bath at 100 c. what is the entropy change of the universe? 3. the process is divided into four stages with heat baths at 25, 50, 75, m and 100°c. what is the entropy change of the universe in this case? 4. if we were to continue this subdivision into an infinite number of heat baths what would be the entropy change of the universe?

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
