A
positive work is done by the ice-water system on the atmosphere and the internal energy of icewater system decreases.
B
positive work is done on the ice-water system by the atmosphere and the internal energy of the ice-water system increases
C
only the internal energy of the ice-water system increases
D
only the internal energy of ice-water system decreases.
Answer
positive work is done on the ice-water system by the atmosphere and the internal energy of the ice-water system increases
Explanation
Solution
The correct option is (B): positive work is done on the ice-water system by the atmosphere and the internal energy of the ice-water system increases
