Answer to Question 1
The amount of heat transferred is DQ = (heat capacity)DT. Given that the
temperatures rise the same amount, the substance with the greater heat capacity will transfer
the greater amount of heat. Therefore, the statement is correct.
Answer to Question 2
This is not true. We have seen that the quality of the energy is not the same.
Electrical energy can all be converted to useful work, but thermal energy cannot. We have
seen that thermal engines operate between temperature reservoirs and that thermal energy is
taken from the high temperature reservoir, work is done, and thermal energy is exhausted to
the low temperature reservoir. The energy rejected to the low temperature reservoir cannot
be used to do work.
