An 8.5 g ice cube at -10°C is put into a
Thermos flask containing 200 cm3
of water at 20°C. By how much has the
entropy of the cube-water system changed when equilibrium
is reached? The specific heat of ice is 2220 J/kg·K.
Tf= 288.73 K
The Attempt at a Solution
I got 6.67 J/k. But I'm not sure thats right.
