Refrigerant$-134$a at $320$ kPa and $40^($@$)$C undergoes an isothermal process in a closed system until its quality is $65\mathrm{.}00$ percent. On a per$-$

unit$-$mass basis, determine the required magnitude of work and heat transfer. Use the tables for R$-134$a$.$

The required magnitude of work is

kJ$//$kg$.$

The required magnitude of heat transfer is
