Since the heat supplied at a slow rate, the temperature of the gas doesn't change much. It's an isothermal process. And all the heat supplied goes to do the work.

Since the volume of gas supports the weight of the piston, the pressure of the gas is same as weight of piston/area.

 

Work done = (Force)(Displacement)

= (1 kg)(9.8 m/s2)(0.1 m ) = 0.98 J

Hence heat supplied is 0.98 J.

sir, in the video you have to ask a question two moles of an ideal gas expands isothermally at 298k,from an initial volume of vi=0.025m3 to a final volume of vf=0.050m3? In the answer n=2.0 moles R=8.31J/(mol.k)can you tell me why the value of n=2.0moles R=8.31j(mol.k).
