Question

Question 4 Some liquid water and an identical mass of ice are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figures (a) - () are sketches of the temperature T of the samples versus time t a. Are any of these plots impossible to produce experimentally? Why? b. Is the equilibrium temperature above, below, or at the freezing point of water? c. In reaching equilibrium, does this liquid partly freeze, fully freeze, or undergo no freezing? d. Does the ice partly melt, fully melt, or undergo no 7 melting? in

Explanation / Answer

a)situation f is impossible as the temperature if ice/water would not drop suddenly.

b)In situation b and c the temperature is at freezing point.

In situation d the temperature is above freezing point.

In situation e the temperature is below freezing point.

c and d)In situation b: liquid partly freeze and no ice melts

In situation c: no liquid freezes and no ice melts

In situation d: no liquid freezes and ice fully melts

In situation e: liquid fully freezes and no ice melts
