Question

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

Answer 1

Dear Student,

◆ Answer -

P = 14475 Pa

◆ Explaination -

# Given -

P1 = 1 atm

P2 = 0 atm

V1 = 5 L

V2 = 30 L

# Solution -

Resultant pressure in both the cylinders will be -

P = (P1V1 + P2V2) / (V1 + V2)

P = (1×5 + 0×30) / (5 + 30)

P = 1/7 atm

P = 14475 Pa

Therefore, resultant air pressure in both cylinders will be 14475 Pa.

Thanks dear...
