If a gas is moved from a large container to a small container but its temperature and number of moles remain the same, wh
2 answers:
Answer : The correct option is, It would increases.
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
From this we conclude that, the pressure is inversely proportional to the volume that means, as the pressure increases the volume will be decreases and pressure decreases the volume increases.
As per question, when the gas is moved from a large container to a small container then the pressure of the gas increases.
Hence, the correct option is, It would increases.

<h3>Further explanation</h3>Given
ΔH fusion and ΔH vaporization of different substances
Required
The substance absorbs 58.16 kJ of energy when 3.11 mol vaporizes
Solution
We can use the formula :
Q=heat/energy absorbed
n = moles
The heat absorbed : 58.16 kJ
moles = 3.11
so ΔH vaporization :
The correct substance which has ΔH vaporization = 18.7 kj / mol is H₂S
(H₂S from the data above has ΔH fusion = 2.37 kj / mol and ΔH vaporization = 18.7 kj / mol)
Answer: pH = 3.15
