Problem $07\mathrm{.}088-$ Air in an insulated piston$-$cylinder device

An insulated piston$-$cylinder device initially contains $330\mathrm{.}0$ L of air at $120$ kPa and $17C.$ Air is now heated for $15$ min by a

$200-$W resistance heater placed inside the cylinder. The pressure of air is kept constant during this process.

Problem $07\mathrm{.}088.$a $-$ Entropy change of air assuming constant specific heats

Determine the entropy change of air assuming constant specific heats. The gas constant of air is $R=0\mathrm{.}287k\frac{J}{k}g*K.($Round the final

answer to three decimal places.$)$

The entropy change of air is

$k\frac{J}{K}.$
