An ice cube (mass 30 g) at 0 degrees celsuis is left sitting on the kitchen table, where it graduallyy melts. The temperature in the kitchen is 25 degrees celsuis. Calculate the entropy of the water (from melted ice ) as its temperature rises from 0 degrees celsuis to 25 degrees celsuis.

2. Relevant equations

c(ice)=2.0 J/g*C

c(water)=4.18 J/g*C

delta(S)= Q/T; Q=C*delta(T)=c*m*delta(T)/T

3. The attempt at a solution

delta(S)= Q/T=c*m*delta(T)/T= ((4.18)*(30 g)*(25 Kelvins))/298 Kelvins= 10.52 J/K
