Heat capacity is the energy an object swallows per kelvin of warming: C = Q ÷ ΔT. The rise is a difference, so 10 K and 10 °C are the same number here. The answer describes the whole object — divide by its mass to get the specific heat capacity of the material.

Worked examples

How it's calculated

C = Q ÷ ΔT

  1. StepEnter the heat energy supplied, in joules.Heat energy added=4,184J
  2. StepEnter how far the temperature rose, in kelvin or degrees Celsius.Temperature rise=10K
  3. ResultRead the heat capacity of the whole object in joules per kelvin.Heat energy added=4,184J→418.40J/K

Questions

How do I calculate heat capacity?

Divide the heat energy added by the temperature change it caused: C = Q ÷ ΔT. Joules for the energy and kelvin for the change give the answer in J/K — 4184 J over a rise of 10 K is 418.4 J/K.

What is heat capacity?

It is the heat energy needed to raise the temperature of a whole object by one kelvin, measured in joules per kelvin. A high value means the object stores a lot of heat for a small temperature change.

What is the difference between heat capacity and specific heat?

Heat capacity in J/K belongs to a whole object and grows with the amount of material. Specific heat capacity in J/(kg·K) is per kilogram and depends only on the substance; divide the heat capacity by the mass to get it.

Kelvin or Celsius for the temperature change?

Either, because this field is a difference and a change of 1 K is exactly a change of 1 °C. Degrees Fahrenheit are not interchangeable and must be converted first.

Does heat capacity depend on the size of the object?

Yes, it scales with the amount of material: double the mass of the same substance and the heat capacity doubles. That is why a full kettle needs far more energy than a single cup.
