Same amount of the same sample of water ...

Same amount of the same sample of water is taken in four different conditions. The amount of dis solved oxygen in all cases was analysed. Identify the correct order.

A

Hill station in summer

B

Sea level in summer

C

Sea level in winter

D

Deep sea in winter

Text Solution

Verified by Experts

The correct Answer is:
B
Solubility of a gas in a liquid is proportional to the external pressure and inversely proportional to the external temperature. As atmospheric pres sure is the least at hill stations, solubility is also the least. The solubility is greater in winter than in summer. The solubility of oxygen in water is maximum in deep sea in winter. The correct order is deep sea in winter `gt` sea level in winter `gt` sea level in summer `gt` hill station in summer.
Hence, the correct option is (b).
