A cylinder of 5 L capacity, filled with air at NTP is connected with another evacuated cylinder of 30 L capacity. The resultant air pressure in both the cylinders will be

A

10.8 cm of Hg

B

14.9cm of Hg

C

21.8 cm of Hg

D

38.8 cm of Hg

Text Solution

Verified by Experts

The correct Answer is:
A
According to Boyle.s law
`P_1V_1 = P_2V_2 , 76 xx 5 = P_2 xx 35`
`P_2 = (76xx5)/(35) rArr P_2 = 10.8cm of Hg`
