An ideal gas is kept in a long cylindrical vessel fitted with a frictionless piston of cross-sectional area `10cm^(2)`and weight 1kg. The length of the gas column in the vessel mow taken into a spaceship revolving round the earth as satellite. The air pressure in the spaceship is amintained at 100kPa. Find the length of the gas column in the cylinder.

`((P_1)(V_1) = (P_2)(V_2))`
` rArr (mg/A + (P_0)) Al = (P_0)Al'`
` rArr ((1 xx 9.8/10 xx (10^-4))+(10^5)) 0.2 = (10^5)l'`
` (9.8 xx (10^3) + (10^5)) xx 0.2 = (10^5)l' `
` = 109.8 xx (10^3) xx 0.2 =(10^5)l'`
` rArr l' = (1098 xx 0.2/(10^2))`
` = 0.2196m = 0.22m ~~22cm` .

An ideal gas is kept in a long cylindrical vessel fitted with a frictionless piston of cross-sectional area 10cm^(2) and weight 1kg.The vessel itself is kept in a big chamber containing air at atmospheric pressure 100kPa. The length of the gas column is 20cm.if the chamber is now completely evacuated by an exhaust pump, what will be the length of the gas column? Assume the tempaerature to remain constant throughout the process.

A gas is enclosed in a cylindrical vessel fitted with a frictionless piston. The gas is slowly heated for some time. During the process, 10 J of heat is supplied and the piston is found to move out 10 cm. The area of cross-section of the cylinder =4cm^2 and the atmospheric pressure =100kPa .

A gas is enclosed in a cylindrical vessel fitted with a frictionless piston.the gas is slowly heated for some time. During the process, 10 J of heat is suopplied and the piston is found to move out 10cm. Find the increase in the internal energy of the gas , the area of cross section of the gas, the area of cross section of the cylinder=4 cm^(4) and the atmospheric pressure =100 kPa.

In the arrangement shown in figure, the piston can smoothly move inside the cylinder. The mass of the piston is m = 100 g and its cross sectional area is A = 10 cm^(2) . The length of air column at temperature of T = 27^(@)C is 10 cm. Overall length of the cylinder is 20.4 cm. The container is turned upside down and the length of the air column in equilibrium was found to be l at 27^(@)C . Take R = (25)/(3)J mol^(-1) K^(-1) and assume air to be diatomic gas. g = 10 m//s^(2) , atmospheric pressure is 1.01 xx 10^(5) Nm^(2) (a) Find l (b) If the air in the container is supplied heat in upside down position, the piston slowly begins to move down, and ultimately it gets ejected out of the cylinder. Calculate the amount of heat that the air must absorb for the piston to come out.

A diatomic gas is enclosed in a vessel fitted with massless movable piston. Area of cross section of vessel is 1m^2 . Initial height of the piston is 1m (see the figure). The initial temperature of the gas is 300K. The temperature of the gas is increased to 400K, keeping pressure constant, calculate the new height of the piston. The piston is brought to its initial position with no heat exchange. Calculate the final temperature of the gas. You can leave answer in fraction.

A cylindrical tube ofuniform cross sectional area A is fitted with two frictionless pistons, as shown in figure-2.46. The pistons are connected to each other by a metallic wire. Initially the pressure of the gas is equal to atmospheric pressure P_0 and temperature is T^0 . If the temperature of the gas is increased to 2T_0 , find the tension in the wire.

Show a vertical cylindrical vesse seperated in two parts by a frictionless piston free to move along the length of vessel. The length of the cylilender is 90 cm and the piston divides the cylinder in the ratio of 5:4. Each of the two parts of the vessel contains 0.1 mole of an ideal gas. The temoerature of the gas is 300K in each part. Calculate the mass of the piston.(figure)

Air is contained in a vertical piston – cylinder assembly fitted with an electric heater. The piston has a mass of 50 kg and cross sectional area of 0.1 m^(2) . Mass of the air inside the cylinder is 0.3 kg. The heater is switched on and the volume of the air slowly increases by 0.045 m^(3) . It was found that the internal energy of the air increased by 32.2 kJ//kg and that of the piston increased by 0.06 kJ/kg. Assume that the container walls and outer surface of the piston are well insulated and there is no friction. The atmospheric pressure is 100 kPa. Determine the heat transferred by the heater to the system consisting of air and the piston.

Two moles of an ideal monoatomic gas are confined within a cylinder by a massless and frictionless spring loaded piston of cross-sectional area 4 xx 10^(-3)m^(2) . The spring is, initially in its relaxed state. Now the gas is heated by an electric heater, placed inside the cylinder, for some time. During this time, the gas expands and does 50J of work in moving the piston through a distance 0.10m . The temperature of the gas increases by 50K . Calculate the spring constant and the heat supplied by the heater. P_(atm) = 1 xx 10^(5)N//m^(2)R = 8.314 J//mol-K
