Given:
128g sample of water
2808J of heat energy
Required:
Change in temperature
Solution:
This can be solved through the equation H = mCpT where H is the heat, m is the mass, Cp is the specific heat and T is the change in temperature.
The specific heat of the water is 4.18 J/g-K
Plugging in the values into the equation
H = mCpT
2808J = (128g) (4.18 J/g-K) T
T = 5.25 K
