What formula is q = mcΔt?
GeneralClass 12AllAnswered 27 Mar 2026
Answer
This is the heat transfer formula:
- q = heat energy transferred (joules)
- m = mass of substance (kg or g)
- c = specific heat capacity (J/kg·K or J/g·°C)
- Δt = temperature change (K or °C)
This calculates energy required to change a substance's temperature. Not directly work, but related through the first law of thermodynamics.
