Answers

1. No! It’s way too cold — it would freeze instead.	2. Yes! That’s why a room can feel cool.
3. Yes! Much hotter.	4. Yes! It melts quickly at 35°C.
5. Yes! That’s why ice stays frozen.	6. Almost, but not quite.
7. Yes! Lava is hot — but the Sun is way hotter.	8. Yes — just a little!
9. Yes! That’s why oil can fry food.	10. Yes — dangerously hot!
11. Yes — and also evaporate quickly (plus no atmosphere!).	12. Yes! Much colder.
13. Yes! The core is much hotter.	14. Yes — it can flash-freeze or turn into vapor in extreme cold!
