An endothermic process involves which heat flow?

Explanation:
Endothermic processes gain energy by taking in heat from their surroundings. So the heat flow goes into the system from the surroundings, meaning heat is absorbed from the surroundings. If heat were released to the surroundings, that would be exothermic. Temperature changes aren’t a guaranteed feature of endothermic processes, and saying there’s no energy exchange would contradict the idea of heat being absorbed.
