621.4L
56.04mL
Explanation:
Question 1:
Initial volume of gas = 547L
Initial temperature = 331K
Final temperature = 376K
Unknown:
Final volume = ?
Solution:
To solve this problem, we are going to apply Charles's law.
The law states that that "the volume of a fixed mass of gas is directly proportional to its temperature provided that pressure is constant".
Mathematically;
V₁ is the initial volume of gas
T₁ is the initial temperature of gas
V₂ is the final volume of gas
T₂ is the final temperature gas
Assuming that the pressure in the cylinder is constant,
make the unknown the subject of the expression;
Input the values;
V₂ = = 621.4L

Question 2
Given parameters:
Initial pressure = 130kPa
Initial volume = 97mL
Final pressure = 225kPa
Unknown:
Final volume = ?
Solution:
To solve this problem, we are going to apply Boyle's law .
Boyle's law states that "the volume of a fixed mass of a gas is inversely proportional to the change in pressure provided that temperature is constant".
Mathematically;
P₁ V₁ = P₂ V₂
where:
P₁ is the initial pressure
V₁ is the initial volume
P₂ is the final pressure
V₂ is the final volume
Since the unknown is V₂; let us solve for it;
97 x 130 = 225 x V₂
V₂ = = 56.04mL
