B, a physical change because it is not destroying the substance.
<h3><u>Answer;</u></h3>
At room temperature, the solubility of which solute in water would be most affected by a change in pressure?
<h3><u>Explanation;</u></h3>
- As the pressure on a gas confined above a liquid increases, the solubility of the gas increases in the liquid.
- Carbon dioxide gas is most soluble in water under conditions of high pressure and low temperature.
- The solubility of gases decreases with increasing temperature, so the air space inside the cylinder when cold water is used will be less compared to warm water.

Explanation:
Given parameters:
Number of molecules = 7.5 x 10²⁴molecules
Condition = STP
Unknown:
Volume of gas = ?
Solution;
The volume of gas at STP is expressed below;
Volume of gas = number of moles x 22.4
Number of moles = 
Now if we can obtain the value of the number of moles from the expression above, we can plug it back into the equation of the volume of gas at STP;
Number of moles of NH₃ = ![\frac{[tex]7.5 x 10^{24}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Btex%5D7.5%20x%2010%5E%7B24%7D)
}{6.02 x 10^{23} }[/tex]
Number of moles of NH₃ = 12.5moles
Volume of gas = 12.5 x 22.4 = 27.9L
