A sample of gas expands from volume V_(1) to V_(2) . The amount of work done by the gas is greatest when the expansion is

One mole of an ideal gas at 300 K expands isothermally and reversibly from 5 to 20 litres. Calculate the work done and heat absorbed by the gas.

A force F = (10 +0.25x ) is acting on a particle moving along positive X direction . Calculate the work done by this force during a displacement from x = 1 m to x = 4 m .

One mole of oxygen is allowed to expand isothermally and reversibly from 5 m^(3) to 10 m^(3) at 300 K. Calculate the work done in expansion of the gas.

A gas expands from a volume of 3.0 dm^3 to 5.0 dm^3 against a constant external pressure of 3.0 atm. The work done during expansion is used to heat 10 moles of water at a temperature 290 K. Calculate the final temperature of water. Specific heat of water = 4.184 Jg^(-1) K^(-1)

One mole of an ideal gas expands isothermally at 300 K from 1 litre to 101 litres at constant pressure of 1 atmosphere. The work done during this change is (1 lit atrn = 24.2 cals)

A gas is contained in a cyclinder and expands according to the relation rhoV^(13) =constant. The initial pressure and initial volume of the gas are 30atm. And 30L respectively. If the final pressure is 15atm, then calculate the work done on the face of piston by the pressure force of the gas.
