A 6.7 volume of air, initially at 23 degrees celsius and. 98 atm, is compressed to 2.7 L while heated to 125 degrees celsius. What is the final pressure?

dа ta:

V1 = 6.7 liter

T1 = 23° = 23 + 273.15 K = 300.15 K

P1 = 0.98 atm

V2 = 2.7 liter

T2 = 125° = 125 + 273.15 K = 398.15 K

P2 = ?

Formula:

Combined law of ideal gases: P1 V1 / T1 = P2 V2 / T2

=> P2 = P1 V1 T2 / (T1 V2)

P2 = 0.98 atm * 6.7 liter * 398.15 K / (300.15K * 2.7 liter)

P2 = 3.22 atm
