In order to calculate the energy needed, we can use the formula below:
![Q=m\cdot c\operatorname{\cdot}\Delta T]()
Where Q is the heat needed (in Joules), m is the mass, c is the specific heat and DeltaT is the change of temperature.
So, using the given information, we have:
![\begin{gathered} Q=8.56\operatorname{\cdot}4186\operatorname{\cdot}(61.13-33.52)\\ \\ Q=8.56\operatorname{\cdot}4186\operatorname{\cdot}27.61\\ \\ Q=989325.94\text{ J} \end{gathered}]()
Therefore the energy needed is 989325.94 Joules.
