Pressure -- open a window on a box

[opsops]

Homework Statement

if i have a box of:
volume V1= 2 m3
pressure p1= 0.5 KPa
temperature T1= 80° C
with a window of A=0.2 m2

if i open the window what is the time for pressure box= pressure atmosphere?
temperature atmosphere T2= 25°C
pressure atmosphere P2=101kPa

Homework Equations

Q=V3/time [m3/sec]
V3 volume air goes inside the box

V1p1=V3p3=V3p2
V3=(V1p1)/p2
them
time=V3/Q=(V1p1)/(p2Q)

but Q? i don't understand

Hi opsops. Welcome to Physics Forums.

That is an interesting question you have. You made it up, did you?
