Specific Heat Calculator
Use Q = m·c·ΔT to solve for heat energy, mass, specific heat or temperature change. You can also estimate the final temperature when two materials mix.
How do you calculate specific heat?
For a temperature change without a phase change, use Q = m·c·ΔT, where Q is heat energy, m is mass, c is specific heat capacity and ΔT is the temperature change. The mixing mode assumes constant properties and an ideal insulated system unless you enter heat loss.
Frequently asked questions
How do you calculate specific heat?
For a temperature change without a phase change, use Q = m·c·ΔT, where Q is heat energy, m is mass, c is specific heat capacity and ΔT is the temperature change. The mixing mode assumes constant properties and an ideal insulated system unless you enter heat loss.
Are my measurements uploaded?
No. The calculations run in this browser. The entered values are not uploaded or saved by this tool.
What is the specific heat formula?
The sensible-heat equation is Q = m·c·ΔT. Multiply mass by specific heat capacity and temperature change to estimate energy transferred when the material does not change phase.
How do you find the final temperature when two materials mix?
For an ideal insulated mix with no phase change, balance the heat gained and lost. This calculator weights each starting temperature by mass × specific heat and lets you enter heat lost to the surroundings.
Does this calculator handle melting or boiling?
No. It assumes each material keeps one constant specific heat and does not change phase. Melting, boiling, evaporation, chemical reactions and temperature-dependent heat capacity need a more detailed model.
