WebAug 2, 2024 · We can use heat = mc Δ T to determine the amount of heat, but first we need to determine Δ T. Because the final temperature of the iron is 73.3°C and the initial temperature is 25.0°C, Δ T is as follows: ΔT = Tfinal − Tinitial = 73.3°C − 25.0°C = 48.3°C The mass is given as 150.0 g, and Table 7.3 gives the specific heat of iron as 0.108 … Webq = mcΔT. In this equation: q is the enthalpy change of the reaction, measured in J. m is the mass of X, measured in g. c is the specific heat capacity of X, measured in J g -1 K -1. ΔT is the temperature change of X, measured in K. Specific heat capacity, c, is the energy needed to raise the temperature of one gram of a substance by one kelvin.
