The amount of energy needed to increase the temperature of a substance by

is given by:

where
m is the mass of the substance
Cs is the specific heat capacity of the substance

is the increase in temperature
In our problem, m=50.0 g,

(specific heat capacity of water) and

, therefore the amount of energy needed is
