A gas inside a cylinder$-$piston is used in a thermodynamic cycle of $3$ processes:

$1-2$: Constant volume, V$=0\mathrm{.}028$m$3,$ U$2-$U$1=-26\mathrm{.}4$kJ

$2-3$: Expansion with PV$=$C where C is constant, U$3=$U$2$

$3-1$: Constant pressure, P$=1\mathrm{.}4$ bar and W$=-10\mathrm{.}5$kJ

Determine the heat and work in each process, in kJ
