Question

which would most likely result from extremely hot water, used to cool, a nuclear reactor, by pumped into a local lake? a Fish kill due to lowered dissolved oxygen, more fish because of warmer water, or an increase in fish population due to dissolved oxygen

Answer 1

A fish kill due to lowered dissolved oxygen is the most likely result from extremely hot water used to cool a nuclear reactor and pumped into a local lake. The hot water can reduce the amount of dissolved oxygen in the water, making it difficult for fish to breathe. This can lead to a fish kill event where many fish die due to suffocation.
