Homework Answers
By comprasing ,mass remain same but volume gets decreased, and we know density is mass / volume therefore density will get increased. Because density is inversely proportional to volume.
By comprasing ,mass does not change therefore no of mole does not change.

This question is about work and pressure A frictionless piston cylinder contains a gas at a pressure of 200 kPa. The cross-sectional area of the piston is 0.04 m². Heat transfers to the gas, and as a result, the piston and load are raised through a distance (*) of 0.4 m. Assume the atmospheric air pressure to be 100 kPa.

A cylinder with a movable piston contains 17.5 moles of a monatomic ideal gas at a pressure of 1.66 × 105 Pa. The gas is initially at a temperature of 300 K. An electric heater adds 46600 J of energy into the gas while the piston moves in such a way that the pressure remains constant. It may help you to recall that CPCP = 20.79 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is...

A cylinder of volume 1.00m^3 contains 320 g of oxygen gas (O_2) at a temperature of 27.0 degree C. The atomic mass of oxygen is 16 u. (1u = 1.66 times 10^-27 kg) What is the pressure exerted by the gas on the walls of the container? If the volume of the cylinder is reduced to half its original value by pushing down on a piston and the pressure exerted by the oxygen gas on the walls of the cylinder...

A piston/cylinder arrangement with an cross sectional area of 1 mạ contains carbon dioxide at 200 kPa and 290 K. The cylinder has a thick piston that initially held by a pin as shown in Figure 1. The metal piston has a density of 8000 kg/mº, standard acceleration of gravity, &c is 9.81 m/s and the atmospheric pressure is 101 kPa. The pin is now removed, allowing the piston to move and after a while the gas returns to 290...
