Answer 1

Answer:7 ATM for 5 question

Explanation:

PV = P1V1 + P2V2

P(5L + 10L) = 5(9) + 10(6)

P=105/15

=7 ATM

9th ques answer

Initially at lower end

P = 76cm of Hg + 76cm of air = 152cm

T = 300K

V=V12

Where V1 is the volume of the cylinder

Finally at lower end

P = 76cm of air + 38cm of Hg = 114 cm

T = ?

V=3V14

∴P1V1T1=P2V2T2

152×V12×300=114×3V14×T

∴T=114×3×2×300152×4

= 337.5K

Hence answer is

337.5k
