The pressure of a given mass of gas changes from 300Nm^-2 to 120Nm^-2 while the temperature drops from 127°c to -73°c.
The ratio of the final volume to the initial volume is?

since PV = kT, PV/T = k remains constant. So,
300V<sub><sub>1</sub></sub>/(127+273) = 120V<sub><sub>2</sub></sub>/(-73+273)
Now just solve for V<sub><sub>1</sub></sub>/V<sub><sub>2</sub></sub>
300V<sub><sub>1</sub></sub>/(127+273) = 120V<sub><sub>2</sub></sub>/(-73+273)
Now just solve for V<sub><sub>1</sub></sub>/V<sub><sub>2</sub></sub>
