To increase the pressure inside the container at constant temperature, the student will have to push down the gas piston. This will result in a decrease in the volume occupied by the gas molecules. This observation is also stated by Boyle's Law wherein he states that at constant temperature, pressure and volume are inversely proportional to each other. Thus, the row of the table that should be filled with the corresponding observation is <span>b.row 1, volume decreases when pressure increases. </span>

<h3><u>Answer;</u></h3>
pH = 4.38
<u>Explanation;</u>
Consider that;
[H3O+] = 10-pH mol/L
Therefore; the pH is the -log of the [hydronium ion].
pH = - log [H3O+]
Thus;
pH = - log (4.2 × 10^–5)
<u> = 4.38 </u>

The answer: A
Explanation: fossil fuels need to be burned to release the energy stored in them, Which leads to smoke casting cans gas being pumped into the air. Unfortunately, burning fossil fuels Releases harmful particles and greenhouse gases into the atmosphere, resulting in adverse affects humans and earth as a whole.
