Perform calculations similar to those performed in part 1 to determine c
antifreeze
, the spe-
cific heat of antifreeze.
c
antifreeze
= ____________
Questions
1. How do the specific heats of the samples compare with the specific heat of water?
2. Discuss any unwanted heat loss or gain that might have effected your results.
3. From your measured specific heat for antifreeze, which should be the better coolant
for an automobile engine, antifreeze or water? Why is antifreeze used as an engine
coolant?
