Answer:
200cm³
Explanation:
Given parameters;
Initial volume = 100cm³
Initial pressure = 120kPa
Final pressure = 60kPa
Unknown:
Final volume = ?
Solution:
The temperature is constant, we apply Boyle's law to solve this problem.
Boyle's states that "the volume of fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are the pressure and volume
1 and 2 are the initial and final values;
Now insert the parameters and solve;
120 x 100 = 60 x V₂
V₂ = 200cm³
