Explanation / Answer

1] Ideal gas equation PV = nRT, P and T is low then Volume V and moles n are constant or normal.

2] Ideal gas equation PV = nRT

when additional air is filled, number of moles n increases, pressure P also increases.

3] P is proportional to T,

P2 = P1*T2/T1 = 1*(-10+273)/(30.8+273)

= 0.866 atm answer
