Given :

  • Initial volume when oxygen was collected ( V₁ ) = 600 L
  • Initial temperature when oxygen was collected ( T₁ ) = 27° C
  • Final temperature of oxygen collected ( T₂ ) = 23°C

To find :

Final volume ( V₂ ) of oxygen collected

Solution :

Note - As we are not given any information about pressure, we will assume that pressure remains same during whole process.

According to Charles's law , under constant pressure volume of gas is directly proportional to its temperature in Kelvin scale.

➝ V ∝ T

\sf \implies \:\dfrac{V_1}{V_2} \:  = \:  \dfrac{T_1}{T_2}

Now. first of all we need to convert temperature into Kelvin scale.

  • T₁ = 27° C

➝ T₁ = 27 + 273 K

➝ T₁ = 300 K

  • T₂ = 23°C

➝ T₂ = 23° + 273

➝ T₂ = 296 K

________________________________

\sf \implies \:\dfrac{600\:L}{V_2} \:  = \:  \dfrac{300\:K}{296\:K}

\sf \implies \:V_2\:  = \:  \dfrac{296\:K}{300\:K} \times 600 \: L

\sf \implies \:V_2\:  = \:  296 \:  \times  \: \dfrac{600\:}{300\:}  \: L

\sf \implies \:V_2\:  = \:  296 \:  \times  2  \: L

\sf \implies \:V_2\:  = \:  \bold{ 592  \: L}

ANSWER : 592 L
