An insulated cylinder contains nitrogen ...


An insulated cylinder contains nitrogen gas which is sealed on the top by a heavy metal piston of mass m. piston is free to move with negligible friction, initial height of the piston is 0.3 m at temperature `27^(@)C` when it is givenn some heat with the help of an electrical circuit piston slowly rises to height 0.5 m above the bottom of the cylinder. During expansion of te gas, net heat absorbed by the nitrogen gas:

A

Equal to work done by nitrogen gas on the piston

B

Greater to work done by nitrogen gas on the piston.

C

Less to work done by nitrogen gas on the piston

D

Will be always twice of the work done by the gas on the piston.

A cylinder containing an ideal gas is in vertical position and has a piston of mass M that is able to move up or down without friction (figure). If the temperature is increased

A closed hollow insulated cylinder is filled with gas at 0^(@)C and also contains an insulated piston of negligible weight and negligible thickness at the middle point. The gas on one side of the piston is heated to 100^(@)C . If the piston moves 5 cm the length of the hollow cylinder is

A freely sliding massive piston is supported by a spring inside a vertical cylinder as shown. When all air is pumped out of the container, the piston remains in equilibrium with only a tiny gap between the piston and the bottom surface of the cylinder. An ideal gas at temperature T_(0) is slowly injected under the piston so that it rises to height h_(0) (see figure). Calculate the height of the piston from the bottom of the container if the temperature of the gas is slowly raised to 4 T_(0) .

A weightless piston divides a thermally insulated cylinder into two equal parts. One part contains one mole of an ideal gas with adiabatic exponent gamma , the other is evacuated. The initial gas temperature is T_0 . The piston is released and the gas fills the whole volume of the cylinder. Then the piston is slowly displaced back to the initial position. Find the increment of the internal energy and entropy of the gas was resulting from these two processes.

A vertical closed cylinder is separated into two parts by a frictionless piston of mass m and of negligible thickness. The piston is free to move along the length of the cylinder. The length of the cylinder above the piston is l_(1) , and that below the piston is l_(2) , such that l_(1)gtl_(2) . Each part of the cylinder contains n moles of an ideal gas at equal temeprature T. If the pistion is stationary, its mass, m, will be given by : (R is universal gas constant and g is the acceleration due to gravitey)

A gas is contained in a metallic cylinder fitted with a piston.the piston is suddenly moved in to compress the gas and is maintained at this position. As time passes the pressure of the gas in the cylinder

The piston cylinder arrangement shown contains a diatomic gas at temperature 300 K The cross sectinal area of the cylinder is 1m2. Initially the height of the piston above th base of the cyclinder is 1 m. The temperature is now raised to 400 K at constant pressure. There is no heat loss in the process.. Find the new height (in m) of the piston above the base of the cylinder.
