## Homework Statement

a fridge at temp 2 C is in a kitchen of temp 22 C, over 1 hour 75 Kj of energy is supplied,

calculate the change in entropy of the fridge & kitchen

## Homework Equations

S = Qrev / T

Fridge Temp in Kelvin 275.15 K

Kitchen Temp in Kelvin 295.15 K

## The Attempt at a Solution

so S1 = 75 Kj / 275.15

and S2 = 75 Kj / 295.15

But this doesnt seem to make sense as i would expect the entropy in the fridge to go down and the kitchen to go up but these are both positive values
