Problem $04\mathrm{.}081-$ Energy balance for air in a piston$-$cylinder device with stops

A piston$-$cylinder device, whose piston is resting on a set of stops, initially contains $5\mathrm{.}000$ kg of air at

$200$ kPa and $27C.$ The mass of the piston is such that a pressure of $400$ kPa is required to move it$.$

Heat is now transferred to the air until its volume doubles. The gas constant of air is

$R=0\mathrm{.}287$kPa$*\frac{m^3}{k}g*K($Table A$-1).$

Problem $04\mathrm{.}081.$a $-$ Find work and heat transfer

Determine the work done by the air and the total heat transferred to the air during this process.

The work done by the air during this process is

The total heat transferred to the air during this process is
