Question

22) The Second Law of Thermodynamics states that in spontaneous reactions, the universe tends toward a state of greater disorder. When the entropy increase in the system is greater than the entropy decrese in the surroundings, the entropy of the universe will increase.
A) a release of heat by the system
B) an absorption of heat by the system
C) an increase in disorder in the system
D) a decrease in randomness in the system
E) none of the above

16) A 73 g sample of water with a temperature of 5.3°C is added to 271 g water at 59°C in an insulated container. What is the final temperature after thermal equilibrium is reached?
A) 0.021°C
B) 17°C
C) 32°C
D) 48°C
E) 224°C

Answer 1

For #22 we need the last part of the question.

#16
T = [ (73 g X 5.3°C) + ( 271 g X 59°C) ] / ( 73 g + 271 g)
T = 48°C
