Answer #1

As we know that water will exist in 3 phases like solid, liquid and vapor and it will inter change between these 3 phases at different conditions without changing the composition.

It means that in a physical change there is no change in internal composition (H2O) and physical properties like shape temperature, state color etc only will change .

So, freezing of water is a physical change

Where as in chemical changes, internal composition will change Ex: Rusting of Iron

You design a steam engine that uses water at the freezing point and water at the boiling point (both at regular atmospheric pressure) to generate useful work. Calculate the Carnot efficiency of this heat engine. You invent a superheated steam engine that can generate steam as hot as 590 °C. If this heat engine uses water at the freezing point as the cold object, calculate the Carnot efficiency of this new heat engine.

Use the 2nd Law to determine whether the freezing of supercooled water (i.e. in the liquid phase) at -4 ºC is spontaneous. Hints: The entropy change of the surroundings is equal to –qsys, actual/T, while the entropy change of the system must be determined by finding a reversible path. When are phase transitions reversible?
