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.

Answer 1

The answer is a.145.45cm^3

Answer 2

Answer:

option A

Step-by-step 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 =$\dfrac{20\times 16}{2.2}$

                               V₂ = 145.45 cm³

hence, the correct answer is option A
