Calorimetry heat calculator
The workhorse of thermochemistry: heat equals mass times specific heat times the temperature change.

Show the working
- Mass = 500
- Specific heat capacity = 4.184
- Temperature change = 25
- Heat = 500 * 4.184 * 25 = 52 300
- Same energy = 52 300 / 1000 = 52.3
- Same energy = 52 300 / 4184 = 12.5
- Same energy = 52 300 / 3600 = 14.5278
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- q = m c delta T
A positive answer means heat went in. Reverse the sign of the temperature change for cooling.
