A gas is contained in a vertical, frictionless
Chapter 3, Problem 23P(choose chapter or problem)
A gas is contained in a vertical, frictionless piston–cylinder device. The piston has a mass of 4 kg and a cross– sectional area of 35 \(\mathrm{Cm}^{2}\). A compressed spring above the piston exerts a force of 60 N on the piston. If the atmospheric pressure is 95 kPa, determine the pressure inside the cylinder.

QUESTION:
A gas is contained in a vertical, frictionless piston–cylinder device. The piston has a mass of 4 kg and a cross– sectional area of 35 \(\mathrm{Cm}^{2}\). A compressed spring above the piston exerts a force of 60 N on the piston. If the atmospheric pressure is 95 kPa, determine the pressure inside the cylinder.
ANSWER:
Step 1 of 5
Mass of the piston m = 4 kg
Area of cross section of the piston A = or
Force exerted by the spring F = 60 N
The atmospheric pressure kPa
Acceleration due to gravity g = 9.8
