Heating equation
WebIt’s an algebra problem where we’re solving for ΔT in the heat capacity equation. So, q = mCΔT, given equation q/(mC) = ΔT, divide by m and C for both sides of the equation. So ΔT is solved for then we substitute the values in to get a numerical answer. (1.0 x 10^(2))/(10.0*0.90) = 11.111… or 11 when rounded for sig figs. Hope that helps.
