Problem $07\mathrm{.}029-$ Entropy change of refrigerant, cooled space and total entropy change.

Refrigerant$-134$a enters the coils of the evaporator of a refrigeration system as a saturated liquid$-$vapor mixture at a pressure of $140$ kPa $.$ The refrigerant absorbs $200\mathrm{.}0$ kJ of heat from the cooled space, which is maintained at $\backslash (-10^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ),$ and leaves as saturated vapor at the same pressure.

Problem $07\mathrm{.}029.$a $-$ Entropy change of the refrigerant in an evaporating process

Determine the entropy change of the refrigerant. Use the tables for R$-134$a$.($Round the final answer to four decimal places.$)$

The entropy change of the refrigerant is
