Warm, still water holds ______ oxygen than cold, fast-flowing water.
- a. more
- b. less
Introduction: Water is colorless, transparent chemical substance that contains one molecule of oxygen and two molecules of hydrogen atoms joined by covalent bonds.
Reason for correct answer:
The solubility of any gas in cold water is higher than in warm water. The kinetic energy of the gas molecules increase with increase in temperature. Hence in warm water, there are larger spaces between the water molecules where the oxygen molecules go away from the water.
Option b. is given as ālessā. Therefore, option b. is correct...
