How many grams of water at 25°C must be added to a Dewar flask(isolated system) containing 20 g of ice at -5°C tosatisfy the conditions in (a) through (d)? Compute the entropychange in each case.
Predict the sign of ΔS in each case before doing thecalculation.
a) The final temperature is -2°C; all the water freezes.
b) The final temperature is 0°C; half the water freezes
c) The final temperature is 0°C; half the ice melts
d) The final temperature is 10°C; all the ice melts
