Question

Chloe Beaumont · Accepted Answer

Final Answer : A, Explanation :  When a substance freezes to a solid state, it releases heat energy to its surroundings because it is going from a higher energy state (liquid) to a lower energy state (solid). This process is exothermic. When ice melts, it absorbs heat energy, not releases it, making Technician B's statement incorrect.
