Heat Transfer Calculator — Q = mcΔT
Heating something takes energy proportional to its mass, its material's specific heat, and the temperature change you want.
Heat Transfer Calculator — Q = mcΔT
How to interpret the result
Heating 1 kg of water by 1 °C takes 4,186 J — water's huge specific heat is why oceans moderate climate and why pasta water takes so long to boil.
Assumptions
- No phase change (no melting/boiling during the interval)
- Specific heat constant over the range
- °C option is a temperature difference, equal in size to kelvin
