Tbh I would pick A because the liquid* decreases. B doesn’t increase
Answer:

- <u><em>Concentrated</em></u>
Explanation:
Concentration measures the amount of solute in a solution. There are many expressions of concentration. Some of then are percentage (mass/mass, volume/mass, volume/volume), molarity, molality, mole fraction, among others.
When a solution has a high concentration it is said that it is <em>concentrated; </em>when a solution has a low concentration is is said that is is diluted.
Concentrated solutions expressed in percentage typically have about 80 - 90% (or more) of solute.
Diluted solutions expressed in percentage, tipylcally have about 10% - 20% or less.
But they are not fixed limits. You might say that a 85% solution is concentrated. Acids at 75 % sure are concentrated.
Hence, a 93.3% solution is concentrated, definitely.
(A) OPTION A must be your answer.
Answer is 231.8 K
<em>Explanation</em>
We can use Charle's law to solve this problem.
<span>Charle's law says
"at a constant
pressure, the volume of a fixed amount of gas is directly proportional to its
absolute temperature".
V α T
Where V is the volume and T is the temperature
in Kelvin of the gas. We can use this for two situations as,
V</span>₁/T₁ = V₂/T₂<span>
</span>V₁ = 1.00 L<span>
T</span>₁ =
?<span>
V</span>₂ = 1.10 L<span>
T</span>₂ = 255 K (Since the unit of the given temperature is missing in the question, thought that the given temperature is in Kelvin)<span>
<span>
By applying the
formula,
</span>1.00 L / </span>T₁ = 1.10 L / 255 K
<span>
</span>T₁ =
(1.00 L / 1.10 L) x 255 K<span>
</span>T₁ = 231.8 K
<span>
Hence, the initial temperature is 231.8 K.
</span><span>
Assumption : the pressure of the gas is a constant.

Answer:
D) the high specific heat of water caused by hydrogen bonding
Explanation:
- The water has a higher specific heat and is due to the bonding of H2 molecules by the water. When the bonding is broken the heat is released and water molecules can move freely.
- This leads to a decline in the temperatures and thus the heat is released in winters and coastal climates are considered to be milder than terrestrial climates. <u>As the energy is released on condensation</u>.
