Answer:
Undergrowth of water plants hypoxia
Low levels of oxygen.
Explanation:
Eutrophication occur when lake or river has adequate nutrients that will encourage the growth of water plants i.e algae which lead to the depletion of dissolved oxygen in the lake. The growth of algae is increased due to availability of carbondioxide or phosphorus or nutrients required for photosynthesis. This result in tainted drinking water,hypoxia and degradation of recreational activities.

Answer:
Explanation:
When the sample of hot metal is placed inside the water, the metal gives off heat to the water: the temperature of the metal decreases while the temperature of the water increases, until the two reach an equilibrium temperature.
The heat given off by the metal is equal (in magnitude) to the heat absorbed by the water, so we can write:
where:
is the mass of the metal
is the specific heat of the metal
is the initial temperature of the metal
is the equilibrium temperature
is the mass of the water
is the specific heat of water
is the initial temperature of the water
And solving for , we find the specific heat of the metal:
