Not what you're looking for?

Ask Custom Question

A gas is contained in a vertical, frictionless piston cylinder device. The piston has a mass of 4 kg and cross-sectional area of 35 cm^2. A compressed spring above the piston exerts a force of 60 N on the piston (as seen in Figure P1-73 attached). If the atmospheric pressure is 95 kPa. determine the pressure inside the cylinder. Please show the steps and full explanation to help my understanding.
Answer: 123.4 kPa
