Problem 1:
200 grams of boiling water and 100 grams of ice-cold liquid water are combined in a sealed thermos bottle.
(a) What is the final (equilibrium) temperature in the thermos?
Hints:C = specific heat of water = 4.186 J/gm0K
(b) What is the change in entropy for the parts (hot water and cold water) of the system, and for the system as a whole?
Hints: HF = 333.55 J/K, C = 4.19J/g
Problem 2:
(a)What is the maximum possible efficiency of a steam engine operating between the temperatures of freezing water (0C) and burning books (451F ~ 233C)?
(b)What is the maximum possible efficiency of a steam engine operating between the temperatures of boiling water (100C) and burning books (451F ~ 233C)?
(c) Which operating range is more efficient? Why?
Hint: 273K= 0C
