`N_(2)` is found in a litre flask under `100 k Pa` pressure and `O_(2)` is found in another `3 litre` flask under `20 K Pa` pressure. If the two flask are connected, the resultant pressure is

A

310 kPa

B

210 kPa

C

420 kPa

D

265 kPa

Text Solution

Verified by Experts

The correct Answer is:
D
`P_("total") = (P_1V_1 + P_2V_2)/(V)`
`= (100 xx 1 + 320 xx 3)/(1+3) = 265kPa.`
