WebThe heat change, q, in a reaction is given by the equation q = mcΔT; where m is the mass of the substance that has a temperature change ΔT and a specific heat capacity c. Students … WebTo calculate the specific heat of the selected substance, we can use the following formula: c = \dfrac {\Delta Q} {m \times \Delta T} c = m×ΔT ΔQ where: c c - specific heat of the substance, \Delta Q ΔQ - amount of heat delivered, m m - mass of the heated sample, \Delta T ΔT - noted temperature change.
