Basic physics: ÄH=MS ÄT
Change in heat equals Mass times Specific Heat times Change in
temperature.
Call "20 sq cm of 5.25" Case A and "25 sq cm of 5.35" Case B. The question
then becomes, Which is greater, ÄH=MAS ÄT or ÄH=MBS ÄT ? T and S in this
problem are constant in both cases, so the question boils down to which has
more mass,, Case A or Case B? Obviously a tighter, more condensed pattern
(Case A) has more mass than the more spacious configuration (Case B). So
the answer to Mike's question is, Yes.
