- Solubility of gases in water decreases as temperature increases. Therefore, less oxygen can dissolve in hot water. - Higher water temperatures increase the metabolic rates of fish and other aquatic organisms, which increases their demand for oxygen. - The combined effect of reduced oxygen availability and increased oxygen demand can lead to stress, suffocation, and death of aquatic life.
Thermal pollution which involves release of excessive amounts of heated water in aquatic systems is harmful. It is because hot water:

- As per the safe drinking water guidelines issued by the Bureau of Indian Standards, Government of India, what is the acceptable pH value of drinking water? Ans: B pH is a measure of how acidic or basic water is. A pH of 7 is neutral. Values below 7 indicate acidity, and values above 7 indicate alkalinity. Maintaining pH within the acceptable range is important for water potability and preventing corrosion in pipes. 337. Sewage treatments generally involve _____. 1. Algal-bacterial symbiosis 2.
