Answer:
744.9 mmHg ≅ 745 mmHg
Explanation:
The base to solve this, is the Ideal Gases Law. The mentioned formula is:
P . V = n . R . T
To compare two situations, we can propose:
For the first situation P₁ . V₁ = n₁. R . T₁
For the second situation P₂ . V₂ = n₂ . R . T₂
As the sample has the same moles and R is a constant value, we can avoid them so: (P₁ . V₁) / T₁ = (P₂ . V₂) / T₂
We need to make Tº unit conversion:
25ºC + 273 = 298K
We replace data → (370 mL . 1020 mmHg) / 298K = (P . 510 mL) / 300 K
(377400 mL.mmHg / 298K) . 300 K = P . 510 mL
379932.8 mL . mmHg = P . 510 mL
(379932.8 mL . mmHg) / 510 mL = P → 744.9 mmHg
Temperature and salinity changes the density of water.
<h3>Effect of Temperature and salinity on water</h3>
Temperature and salinity directly affect density of water. Water that low temperature is more denser than water that has high temperature while on the other hand, Freshwater which has no salt is less denser than seawater which has more salt concentration so we can conclude that temperature and salinity changes the density of water.

Answer:
Because it is closer to earth than the other blue giant stars.
Explanation:
The sun is closer to earth than any other big star which means we see it bigger.
