10 gm. of steam at 100°C is blown into 90 gms. of water at 0°C...
Given m1 = 10 gm., T1= 100°C = 373 K
m2 = 90 + 10 = 100 gm., T2 = 0°C = 273 K.
Let the final temperature be T K.
10 x 540 + 10 (373 - T) = 100 (T - 273)
T = 331.2 K.
Now (i) Change in entropy when temperature of water and calorimeter increases from 273 K to 331.2 K.
(ii) Change in entropy when 10 gms. steam at 373 K condenses to water at the same temperature
where -ve sign indicates that the entypy decreases.
(iii) Change in entropy when 10 gm. water is cooled from 373 K to 331.2 K.
or dS3 = - 1.188 cal/K
The net change (or increase in entropy)
dS = dS1 + dS2 + dS3= + 19.324 - 14.477 - 1.188 = + 3.659 cals./K.
m2 = 90 + 10 = 100 gm., T2 = 0°C = 273 K.
Let the final temperature be T K.
10 x 540 + 10 (373 - T) = 100 (T - 273)
T = 331.2 K.
Now (i) Change in entropy when temperature of water and calorimeter increases from 273 K to 331.2 K.
(ii) Change in entropy when 10 gms. steam at 373 K condenses to water at the same temperature

(iii) Change in entropy when 10 gm. water is cooled from 373 K to 331.2 K.

The net change (or increase in entropy)
dS = dS1 + dS2 + dS3= + 19.324 - 14.477 - 1.188 = + 3.659 cals./K.
