PV=kT, so PV/T is constant
You want T such that
2*25/(T+273) = 1*20/(120+273)
Calculate the final centigrade temperature required to change 20 litres of gas at 120°C and 1 atmosphere to 25 litres at 2 atmosphere.

Calculate the final centigrade temperature required to change 20 litres of gas at 120°C and 1 atmosphere to 25 litres at 2 atmospheres.
Pressure × Volume / Temperature = Number of molecules
PV / T = N
Convert 120°C to 393.15°K
Original state:
1 atmosphere × 20 Liters / 393.15°K = N moles
Final state:
2 atmosphere × 25 Liters / T°K = N moles (solve for T)
Since N remains constant, we can combine the two statements:
1 × 20 / 393.15 = 2 × 25 / T
Solution:
20 / 393.15 = 50 / T
0.05087116877 = 50 / T
T × 0.05087116877 = 50
T = 50 / 0.05087116877
T = 982.875°K
T = 709.725°C
Pressure × Volume / Temperature = Number of molecules
PV / T = N
Convert 120°C to 393.15°K
Original state:
1 atmosphere × 20 Liters / 393.15°K = N moles
Final state:
2 atmosphere × 25 Liters / T°K = N moles (solve for T)
Since N remains constant, we can combine the two statements:
1 × 20 / 393.15 = 2 × 25 / T
Solution:
20 / 393.15 = 50 / T
0.05087116877 = 50 / T
T × 0.05087116877 = 50
T = 50 / 0.05087116877
T = 982.875°K
T = 709.725°C
