A cube of ice whose edges measure 23.0 mm is floating in a glass of ice-cold water with one of its faces parallel to the water's surface.

(a) How far below the water surface is the bottom face of the block?

(b) Ice-cold ethyl alcohol is gently poured onto the water's surface to form a layer 4.50 mm thick above the water. The alcohol does not mix with the water. When the ice cube again attains hydrostatic equilibrium, what will be the distance from the top of the water to the bottom face of the block?

(c) Additional cold ethyl alcohol is poured onto the water's surface until the top surface of the alcohol coincides with the top surface of the ice cube (in hydrostatic equilibrium). How thick is the required layer of ethyl alcohol?

A 0.130-kg cube of ice (frozen water) is floating in glycerine. The gylcerine is in a tall cylinder that has inside radius 3.20 cm . The level of the glycerine is well below the top of the cylinder. f the ice completely melts, by what distance does the height of liquid in the cylinder change? Express your answer with the appropriate units. Does the level of liquid rise or fall? That is, is the surface of the water above or...

True/False: Because hot water cools down faster than cold water, an ice cube tray filled with hot water will freeze faster than an ice cube tray filled with cold water. Explain your choice. Hint: Although hot water cools down at a faster rate than cold water, it also has to undergo a larger temperature change. As it cools down, what happens to the rate at which it continues to cool down? Explain how a mercury thermometer works. A mercury thermometer...
