as ice melts and changes from solid to liquid, a entropy increases. b kinetic energy decreases. c an exothermic reaction occurs. d the random movement of molecules remains constant.
Answer
Brief Explanations:
Entropy is a measure of disorder. When ice (a more ordered solid) melts into liquid water, the molecules have more freedom to move, increasing disorder and thus entropy. Melting is an endothermic process (absorbs heat), kinetic energy increases as temperature may rise during melting and the random - movement of molecules increases.
Answer:
A. entropy increases.
