It Can Be Shown That the Change in Entropy in Heating

question 7

Multiple Choice

It can be shown that the change in entropy in heating or cooling a sample is given by the relation $\Delta$ S = mc ln (T_F/T_i) ,where m is the mass of the sample,c is the specific heat of the sample,and T_F and T_i are the final and initial temperatures respectively.What is the change in entropy when 10.0 grams of lead with a specific heat of 0.452 J/gm K is heated from 10.0 $^{\circ}$ C to 50.0 $^{\circ}$ C?

• A) 0.45 J/K
• B) 0.60 J/K
• C) 0.90 J/K
• D) 0.30 J/K
