Answer:
the answer is the first one A.
The first democracy was probably the athenian democracy
Because water has a tremendous capacity for holding heat ... much more than land, and much much much more than air.
Since water can hold so much heat . . . and it can only absorb heat or radiate heat
from its surface . . . it takes water a long time to get warmed up in the morning (or
even over several warm days), and a long time to get cooled down at night (or even
over several cold days).
So, say it's the beginning of Summer and getting hot. If there's a large body of
water near you, the water is still cool for several days, and air blowing over it
gets cooled before it blows over the city.
Now, say it's the beginning of Winter and getting cold. If there's a large body of
water near you, the water is still warm for several days, and the air blowing over
it gets warmed before it blows over the city.
That's why places near the ocean coast, or the shore of large lakes, have more
"moderate" climates . . . the Summers there are less hot, the Winters there are
less cold, and the temperature doesn't change fast,
Answer and Explanation:
The principle of constant proportion also referred to as Forchhammer's principle states that although the salinity of various samples of seawater may vary, the ratio of major salts present in the sea water remains same irrespective of the salinity of different samples of sea water that might undergo variation in their salinity.
He clarified that the saltiness of seawater changes because of expansion of freshwater and not because of that the proportion of significant salts like sodium chloride, potassium nitrate, magnesium sulfate changes.
Here, if the salt mentioned is NaCl , at that point we can get the measure of NaCl just by estimating saltiness and taking its product with the extent/level of NaCl that is consistent for ocean water to get the sum.
There are various strategies to quantify salinity like by estimating resistivity or the amount of chlorine present in water.
So, if we need to know the measure of NaCl, we can ascertain by this procedure and here is the importance of Law of constant proportion that as the proportions are equal we can utilize that proportion to figure a specific ion.
