A vertical cylinder pistion system has cross-section S . It contains 1 mole of an ideal monoatomic gas under a pistion of mass M .At a certain instant a heater is switched on which transmits a heat Q per unit constant and the system is thermally insulated.

Two moles of an ideal monoatomic gas are contained in a vertical cylinder of cross sectional area A as shown in the figure. The piston is frictionless and has a mass m. At a certain instant a heater starts supplying heat to the gas at a constant rate q J//s . Find the steady velocity of the piston under isobaric condition. All the boundaries are thermally insulated.

A Perfect gas is enclosed in a vertical cylinder filled with a piston of mass m. The gas is heated by passing constant current I through a heating coil of resistance R placed inside the cylinder. At what speed v must the piston move upward in order that temperature of the gas may remain unchanges? Assume ideal insulating walls and piston and there is no fusion.

A vertical thermally insulated cylinder of volume V contain n moles of an ideal monoatomic gas under a weightless piston. A load of weight W is placed on the piston as a result of which the piston is displaced. If the initial temp of the gas is 300K , area of piston is A and atmospheric pressure P_(0) . (take W=P_(0)A ). Determine the value of final temperature of the gas

A resistance coil, connected to an external battery is placed inside an adiabatic cylinder filled with frictionless piston of mass m and containing an ideal gas. A current i flows through the coil, which has resistance R . The speed with which the piston must move in order to keep the temperature of the gas constant will be

An insulator container contains 4 moles of an ideal diatomic gas at temperature T. Heat Q is supplied to this gas, due to which 2 moles of the gas are dissociated into atoms but temperature of the gas remains constant. Then

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

Two cylinder A and B having piston conneted by massless rod (as shown in figure). The cross-sectional area two cylinders are same & equal to 'S'.The cylinder A contains m gm of an ideal gas at Pressure P & temperature T_(0) The cylinder B contain identical gas at same temperature T_(0) but has different mass. The piston is held at the state in the position so that volume of gas in cylinder A & cylinder B are same and is equal to V_(0) . The walls & piston of cylinder A are thermally insulated, whereas cylinder B is maintained at temperature T_(0) reservoir. The whole system is in vacuum. Now the piston is slowly released and it moves towards left & machanical equilibrium is reached at the state when the volume of gas in cylinder A becomes V_(0)/2 Then (here gamma for gas =1.5) If work done by gas in cylinder B is W_(B) & work done by gas in cylinder A is W_(A) then
