Question

When the volume of the gas is 16 cm3, its pressure is 20 L/cm2. Find the volume of the gas when the pressure is 2.2 L/cm2.

a.145.45cm^3
b.704cm^3
c.160cm^3
d.0.007cm^3

Answer 1

the answer is a.145.45cm^3

Answer 2

option A

Explanation:

given,

Volume of gas(V₁) = 16 cm³

Pressure of the gas(P₁) = 20 L/cm²

Volume of Gas(V₂) when pressure(P₂) is 2.2 L/cm²

considering temperature constant

P₁ V₁ = P₂ V₂

20 × 16 =2.2 × V₂

V₂ =
`(20* 16)/(2.2)`

V₂ = 145.45 cm³

hence, the correct answer is option A
