WebDec 23, 2024 · The formula for specific heat looks like this: c = \frac {Q} {m \Delta T} c = mΔT Q. Q Q is the amount of supplied or subtracted heat (in joules), m m is the mass of the sample, and \Delta T ΔT is the difference between the initial and final temperatures. Heat capacity is measured in J/ (kg·K).
