Calculating temperature difference?

Question

it has the final temperature for example at 100.0 C and the starting temperature at 0.0 C, would it be Tf-Ti = 0.0 C? and how would I find the Heat Energy (H) in Calories?

Answer 1

the temp diff is 100 - 0 = 100 degrees celcius

The equation for heat energy in joules is

Heat energy = specific heat of substance * grams of substance * change in temp

1 joule = 0.239005736 calories
