What pressure is required to compress 156.0 liters of air at 2.00 atmosphere into a cylinder

garik1379 [7]

Answer:

option B.

Explanation:

Given,

V₁ = 156 L

P₁ =2 atm

Now, in the cylinder

P₂ = ?

V₂ = 36

Using relation between pressure and volume

$\dfrac{P_1}{V_2}=\dfrac{P_2}{V_1}$

$\dfrac{2}{36}=\dfrac{P_2}{156}$

$P_2 = 8.67\ atm$

Hence, pressure is equal to 8.67 atm.

Hence, the correct answer is option B.
