Question

A mountaineer climbing on the everest, experienced the following facts. Explain each fact with the scientific reason-
A) He found fishes alive below the ice .
B) Time required for cooking was more as he went higher.
C) He saw tubes carrying water broken.

Answer 1

Explanation:

A) He found fishes alive under ice because ice forms a layer on the top of water due to which it floats at the optimal temperature. Below this temperature the density of ice remains the same and it stay on the top keeping the water warm beneath it.

B) He required more time to cook things because external pressure on mountainous regions is high and as we know from the definition of boiling that when external pressure becomes equal to internal pressure of molecules, it starts to boil. Thus, it will take longer for molecules to reach external pressure

C) When water converts to ice, its volume increases. Thus, it expands and puts pressure on the walls of the tube which made it break.
