in what type of reaction or process does heat flow into the system?\n○ combustion\n○ exothermic\n○ condensation\n○ endothermic
Answer
Brief Explanations:
- Combustion: Releases heat (exothermic), so heat flows out.
- Exothermic: Heat flows out of the system.
- Condensation: Gas to liquid, releases heat (exothermic), heat flows out.
- Endothermic: Heat flows into the system as the reaction absorbs heat.
Answer:
D. endothermic
