Specific heat formula q
WebHeat units conversion; Mass units conversion; Temperature difference units conversion; User Guide. This tool will calculate any parameter from the formula for the specific heat capacity of a substance, which includes the amount of heat transferred from or to it, its total mass, the change in temperature, and its specific heat capacity. Formulas WebSpecific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: q = m⋅ c ⋅ ΔT, where q - the amount of heat supplied; m - the mass of the substance; c - the respective substance's specific heat; ΔT - the change in temperature.
