What is the sign convention for work?

An ideal gas is enclosed in a cylinder fitted with a frictionless piston. The piston is connected with a light rod to one plate of capacitor whose other plate is fixed as shown. Initially volume of the gas inside the cylinder is V_0 Atmospheric pressure is P_0 separation between the plates is L, area of the piston as well as of the capacitor plates is A and emf of battery is epsilon . A heater supplies heat to the gas so that pressure of the gas is given as P=P_(0)-("n"epsilon_0epsilon^2)/L^2 when piston is displaced by a distance L/2 . Find value of n.

Two moles of an ideal gas is contained in a cylinder fitted with a frictionless movable piston, exposed to the atmosphere, at an initial temperature T_(0) . The gas is slowly heated so that its volume becomes four times the initial value. The work done by gas is

A gas filled in a cylinder fitted with movable piston is allowed to expand. What is the nature of the work done by the gas?

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 10cm. Find the increase in the internal energy of the gas, the area of cross section of the cylinder= 4 cm^(2) and the atmospheric pressure =100 kPa.

A monoatomic ideal gas, initially at temperature T_1, is enclosed in a cylinder fitted with a friction less piston. The gas is allowed to expand adiabatically to a temperature T_2 by releasing the piston suddenly. If L_1 and L_2 are the length of the gas column before expansion respectively, then (T_1)/(T_2) is given by

Assertion : A quasi static isothermal expansion of an ideal gas in a cylinder fitted with a frictionless movable pistonis a irreversible process. Reason : A process is irreversible only if system remains in equilibrium with the surroundings at every stage.

If the external pressure is more than internal pressure then what will be the sign convention for the work done on a cylinder fitted with a frictionless and weightless pistion containing one mole of an ideal gas?
