`15 L` of gas at `STP` is subjected to four different conditions of temperature and pressure as shown below. In which case the volume will remain unaffected?

Options

A. `273 K`, `2 "bar"` pressure
B. `273^(@)C`, `0.5 atm` pressure
C. `546^(@)C`, `1.5 atm` pressure
D. `273^(@)C`, `2 atm` pressure

Explanation

`V_(1)=15`
`P_(1)=1 atm`
`T_(1)=0^(@)C` or `273.15K`
`P_(2)=2 atm`
`T_(2)=273^(@)C` or `546.15 K`
`V_(2)=?`
`:. V_(2)=(P_(1)V_(1))/(T_(1))xx(T_(2))/(P_(2))=(1xx15)/(273.15)xx(546.15)/(2)=15 L`
