Answer:
40 L
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 20 L
Initial temperature (T₁) = T
Final temperature (T₂) = 2T
Pressure (P) = constant
Final volume (V₂) =?
The new (i.e final) volume of the gas can be obtained as follow:
V₁/T₁ = V₂/T₂
20/T = V₂/2T
Cross multiply
T × V₂ = 20 × 2T
T × V₂ = 40T
Divide both side by T
V₂ = 40T /T
V₂ = 40 L
Therefore, the new volume of the gas is 40 L
