11. A man who has recently moved to live in a city that sits at approximately 1,000 meters above sea level, decides to cook pasta for lunch. He follows the directions that he is used to, and he heats water in a pan and leaves the pasta to cook in the water for 10 minutes. However, after he tastes the pasta, it turns out it is still not fully cooked. Why do you think this happened? 12. a. Is it possible to boil water at room temperature? b. If so, will the boiling water be too hot or will it bearable (not too hot) to touch?
