As shown in the figure, a sealed cylinder of ideal gas is
divided into two parts by a piston that can move up and down
without friction. There is ideal gas in both parts, but the gas
from one part is isolated from that in the other part by the
piston. The volume occupied by the gas in the lower part is twice
that occupied by the gas in the upper part, while the temperature
is the same in both parts. The pressure in the upper part is 4000
Pa, and the weight of the piston is 60.0 N. The piston is in its
equilibrium position. The cross-sectional area of the cylinder is
100 cm

As shown in the figure, a sealed cylinder of ideal gas is
divided into two parts by a piston that can move up and down
without friction. There is ideal gas in both parts, but the gas
from one part is isolated from that in the other part by the
piston. The volume occupied by the gas in the lower part is twice

Pa, and the weight of the piston is 60.0 N. The piston is in its
equilibrium position. The cross-sectional area of the cylinder is
100 cm.
Calculate the ratio of the number of moles of gas in the lower
part to the number of moles in the upper part. (Just state this as
one number. For instance, if the ratio is 2.54:1, you would state
that as 2.54.)

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

ideal gas law questions
Movable piston A cylinder contains an ideal gas that is at room temperature. The cylinder is sealed with a piston of mass M and cross-sectional area A that is free to move up or down without friction. No gas can enter or leave the cylinder. The piston is at rest. Atmospheric pressure (i.e. the pressure of the air surrounding the cylinder) is P. a. In the space provided, draw a free-body diagram for the piston. Ideal...

A gas in a cylinder sealed with a piston having negligible friction has a pressure of 5 atm and a volume of 6 liters. The piston is pushed in order to compress the gas to 1/7 of its original volume. Assume that there is no change in the temperature of the gas. A valve is opened to let enough gas escape until the pressure is reduced back to its original original value of 5 atm. it is 14.3 % Then...

Two moles of oxygen gas are contained in a piston and cylinder device. Initially the gas is at 300. K and sufficient weight is placed on the piston so that the pressure is 2.0 bar. Consider two different processes in which 2000. J of energy in the form of heat are added to the gas in the device. In the second process, the piston is allowed to move freely so that the pressure remains constant. What are the final temperature...

A 19.0- L volume of an ideal gas in a cylinder with a piston is at a pressure of 3.2 atm . Enough weight is suddenly removed from the piston to lower the external pressure to 1.6 atm . The gas then expands at constant temperature until its pressure is 1.6 atm . The change in the internal energy of a system, ΔE , for an isothermal expansion of an ideal gas is 0. Use this information in your calculations...
