Comparing heat capacities in Final 2011

In question 1C it says that ethane has a higher heat capacity than ethane. Why would this be true, wouldn't it be harder to heat up the triple bonds than the double bonds?

You can also calculate it using the bond enthalpy table. Ethane has 6 C-H bonds and 1 C-C Bond, which when added together, will give a higher energy value than will Ethene with 4 C-H bonds, and 1 C=C bond.
