A cylinder is closed at both ends and has insulating walls. It is divided into two compartments by an insulating piston that is perpendicular to the axis of the cylinder as shown in Figure a. Each compartment contains 1.00 mol of oxygen that behaves as an ideal gas with y = 1.40. Initially, the two compartments have equal volumes and their temperatures are T_1i = 585 K and T_2i = 185 K. The piston is then allowed to move slowly...

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...

1)Two rigid tanks of equal size and shape are filled with different gases. The tank on the left contains oxygen, and the tank on the right contains hydrogen. Assume both gases are ideal. The molar masses of oxygen and hydrogen are 32 and 2, respectively. Both containers are at the same temperature. A pressure gauge is pin oxygen hydrogen connected to each tank. Both gauges show a reading of 230 kPa. Is the number of oxygen molecules in the left...

Assume a cylinder is divided into two parts. One part is filled with air, the other is evacuated. If a small hole is opened between the two halves so that the air fills both parts, what will happen to the entropy? a The entropy will increase. b The entropy will stay the same. c The entropy will decrease.

A vertical cylinder contains N atoms of an ideal gas and is closed off by a piston having mass m and area a. The acceleration due to gravity is g. The gas has a heat capacity Cy which is independent of temperature. (Note that the preceding sentence contains the words "heat capacity" and does not contain the words "specific heat.") Neglect the heat capacity of the cylinder and piston, ignore friction, and the entire system is thermally insulated. The piston...

1) A cylinder of length L = 1.00 m and inside radius r = 15.0 cm is filled with 5.00 moles of xenon gas. 1 A disc of the same radius and negligible thickness, with a mass of m = 1.75 kg, is slowly lowered into the cylinder, compressing the gas. Then the rest of the cylinder is filled with 3.00 moles of helium gas, and sealed. Both gasses are maintained at a constant temperature of T = 100.0°C. Assume...

please help with this problem
Ext-2.2 (35 points) An insulated, rigid tank is divided into two compartments by a frictionless, thermally conducting piston. One compartment initially contains 0.6 m' of saturated water vapor at 200 °C and the other compartment contains 0.8 m' of superheated water vapor at 210 bar, 780 °C. The piston is released and equilibrium is attained. The mass of piston is small enough to be neglected in this problem. (a) Draw a schematic diagram of the...
