I couldn't understand the concept of water having a lower boiling point at higher altitude but need to be heated longer for it to get boiled. Isn't it faster to boil it when boiling point decreases? I'm soo confused. Also, thank you for this hard work, I am actually bad at Physics since high school, so my foundation is bad. I couldn't understand fluid mechanics with my own teacher's presentation but since you are showing real life examples and explaining every single thing without thinking "they must know it already" it's sooo much easier and entertaining for me to understand. It also shows that you love to teach. Thank you so much. I appreciate it a lot.

Thanks for the really nice comments! To answer your question. As you said, water boils at a lower temperature at high altitude because of the lower pressure. You are correct: It will take LESS heat input to boil, and will boil FASTER. I was talking about say, cooking noodles in water that's boiling at 80C rather than 100C. It makes sense that the cooking time will have to be longer to soften/cook the noodles. There are cookbooks to help make this adjustment, if you live in a high altitude city. Hope that helps. Thanks again!

Why would you have to boil the noodles for longer if the water boils at 70 C instead of 100 C. Thinking about it intuitively, you'd reckon that your typical college dinner would be ready much faster no?

Take this idea to the limit....Liquid water can boil at 0C, given a low enough pressure. At 0C, the noodles wouldn't cook at all, even though the water was bubbling. In fact, it can be a food safety issue when cooking meat. See: www.fsis.usda.gov/shared/PDF/High_Altitude_Cooking_and_Food_Safety.pdf
