What is specific heat capacity?

Energy required to raise one unit of mass of a substance by one degree.

How is specific heat used in calculations?

Via Q = mcΔT, solvable for any variable given the others.

Why does water have such a high specific heat?

Its molecular structure and hydrogen bonding require large amounts of energy to change temperature.

What Is the Specific Heat Calculator?

The Specific Heat Calculator finds how much heat energy is absorbed or released when a substance changes temperature, using its mass and specific heat capacity — the classic Q = mcΔT equation from chemistry and physics.

Formula Used

Q = m × c × ΔT

Q is heat energy in joules, m is mass in grams, c is specific heat capacity in J/g·°C, and ΔT is the temperature change. Water's specific heat is 4.186 J/g·°C.

How to Use This Calculator

Enter the mass of the substance in grams.
Enter its specific heat capacity in J/g·°C (4.186 for water).
Enter the initial and final temperatures in °C.
Click Calculate to see the heat energy transferred.

Worked Example

Heating 250 g of water from 20°C to 80°C: ΔT = 60°C. Q = 250 × 4.186 × 60 = 62,790 J, or about 62.8 kJ of heat energy absorbed.
