It can be shown that the change in entropy in heating or cooling a sample is given by the relation
= mc ln
where m is the mass of the sample, c is the specific heat of the sample, and
and
are the final and initial temperatures respectively. What is the change in entropy when 20.0 grams of aluminum with a specific heat of 0.9 J/gm K is heated from 10.0
