The equation used for calculating the calories of heat is = mass x specific heat x temperature difference.
Q= m x c x delta T
Q= specific heat
m=mass
c=specific heat
delta T= temperature difference
1ml of water =1 gram of water.
So total water= 60 grams
m= 60 grams
c=specific heat= 1calorie/gram x degree centigrade
delta T= 85-15 degree centigrade
delta T= 70 degree centigrade
Q = 60 grams...
