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
________________________________
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
