25. Which phase change results in the
release of energy?
(1) H2O(s) – H00)
(2) H, O(s) - H, O(g)
(3) H. O(C) H. O(g)
(4) H,0(g) → H2O(C)

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Hi; /c

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
