QUESTION $7$

Refrigerant$-134$a is used in a refrigeration system as a working fluid. Refrigerant enters the coils of the evaporator as a saturated liquid$-$vapor mixture at a pressure of $155$ kPa and leaves as saturated vapor at the same pressure. The refrigerant absorbs $217$ kJ of heat from the cooled space, which is maintained at $\backslash (-15^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ Determine the entropy change of the cooled space. Write your answer in $\backslash (\backslash$mathrm$\{$kJ$\}/\backslash$mathrm$\{$K$\}\backslash )$ with $3$ decimal figures.
