Temperature Change and Heat Capacity: quick check

If 25 kJ is necessary to raise the temperature of a block from $25ºC$ to $30ºC$ , how much heat is necessary to heat the block from $45ºC$ to $50ºC$ ?

Answer it in your own words before you look.

Answer
The heat transfer depends only on the temperature difference. Since the temperature differences are the same in both cases, the same 25 kJ is necessary in the second case.
