The following arrangement is set up in a closed cylinder with a piston on one side:


20.0g of Hydrogen gas (specific heat capacity tex2html_wrap_inline26 ) starting at a temperature of 30 degrees Celsius is heated to 40 degrees Celsius during which the volume of the container grows by tex2html_wrap_inline28 with the pressure remainimg constant at one atmosphere:

a.
What is the work done by the Hydrogen gas?
b.
What is the change in internal energy of the system?
