Answer:
Answer to the question:
Explanation:
A black hole is a finite region of space within which there is a mass concentration high and dense enough to generate a gravitational field such that no material particle, not even light, can escape it.
In ice the molecules are stuck rigidly together and vibrate in place. In liquid water they slide and bump past one another. In water vapor they are much farther apart and they bounce around freely.

C. water
answer a has one sodium atom and one chlorine atom
answer b is a chemical reaction
answer d has only one hydrogen atom and one oxygen atom
Answer:
<h2>352.8 Joules</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 3 × 9.8 × 12
We have the final answer as
<h3>352.8 J</h3>
Hope this helps you
Answer:
An increase in the air temperature will cause water temperatures to increase as well. As water temperatures increase, water pollution problems will increase, and many aquatic habitats will be negatively affected.
Explanation:
Lower levels of dissolved oxygen due to the inverse relationship that exists between dissolved oxygen and temperature. As the temperature of the water increases, dissolved oxygen levels decrease.
Increases in pathogens, nutrients and invasive species.
Increases in concentrations of some pollutants such as ammonia and pentachlorophenol due to their chemical response to warmer temperatures.
Increase in algal blooms (Photo of algal blooms).
Loss of aquatic species whose survival and breeding are temperature dependent.
Change in the abundance and spatial distribution of coastal and marine species and decline in populations of some species.
Increased rates of evapotranspiration from waterbodies, resulting in shrinking of some waterbodies such as the Great Lakes.
