1.0kg of water is heated from 0?C to 100?C. Estimate the change in entropy of the water.

Homework Answers

Answer #1

Heat absorbed by water in temperature rise, dQ=mC dT

Change in entropy=dQ/T

                                =mC dT/T

                                =mC ln(T2/T1)

Here, m=1000g

C=4.184 J/g.?

dS=1000*4.184*ln[(273+100)/273]

=1305.8 J/K
