10 x (70 - 50) = 200 Btu
2250
That will completely depend on how much water there is.
U.S.gallon = 8.33 pounds of water. Therefore to raise the temperature by one degree F will require 8.33 BTU. The initial temperature of 50 F is inconsequential.
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
To raise the temperature of one cc of water requires i calorie of heat . you did not specify the volume.
