Question

(a) Why do mountaineers suffer nose bleeding at high altitudes? (b) How does atmosphere pressure help in drinking juice with straw?​

Answer 1

Answer:

1. As you climb higher, the amount of oxygen in the air decreases. This makes the air thinner and dryer, which can in turn cause the inside of your nose to crack and bleed

2. When you reduce the air pressure inside the straw it causes a suction. The pressure of the air outside the strawis then greater than the air pressure inside the straw, then the liquid goes up the straw. When we drink a fluid we create a vaccum by sucking the air out of the straw.
