A liquid, confined within a cylinder and confined by a piston at the top, has pressure applied to the piston, pushing it downward. The pressure will be:
a. equal everywhere within the cylinder
b. greatest at the bottom of the cylinder
c. greatest on the sides of the cylinder
Equal everywhere within the cylinder
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.

A gas is confined within a piston-cylinder device. The piston rests, stationary atop the gas and has a mass of 6.3 kg and a cross sectional area of 550 mm^2. If atmospheric pressure is 104 kPa, determine the gage pressure of the gas in the cylinder and the absolute pressure of the gas in the cylinder.
Two moles of nitrogen gas at 25°C, confined within a cylinder by a piston maintaining a constant pressure of 1 atm, is heated with 5.30 kJ of energy. Assume all the energy is used to do work of expansion of the gas at 1 atm. What will be the final temperature of the gas? Recall ∆H = ∆E + P∆V and watch your units!
Air contained within a vertical piston-cylinder assembly is shown in Figure 1. On its top, the 10-kg piston is attached to a spring and exposed to an atmospheric pressure of 1 bar. Initially, the bottom of the piston is at x = 0, and the spring exerts a negligible force on the piston. The valve is opened and air enters the cylinder from the supply line, causing the volume of the air within the cylinder...
A cylinder filled with ideal gas is sealed by a piston that is
above the gas. The piston is a cylindrical object, with a weight of
45.0 N, that can slide up or down in the cylinder without friction.
The area of the top (or the bottom) of the piston is 100
cm.
The top of the piston is exposed to the atmosphere, and the
atmospheric pressure is 100 kPa. As shown in the figure, the piston
is tied to...

A large cylinder (shaped like a tuna can) has top and bottom area A and height h, and is made of a uniform material of density ρc. It is floating on a liquid of density ρf . Assume that √ A > h so the cylinder doesn’t tip while the top is facing upwards, and assume that ρc < ρf . (a) What pressure on the bottom of the cylinder would be required to provide enough force to keep the...
(10 ponts) A piston-cylinder that has a piston initially resting on top of a set of stops initially contains 0.35 kg of hellum gas at 100 kPa and 16.8 C. A pressure of 171 kPa is required to lift the piston off the stops. Helium a) At what temperature will the piston begin to move? b) How much heat must be added before the piston starts to rise? c) If the volume of the gas inside the cylinder increases by...
