WebStep 1: Identify what is given in the problem. Q = 50. J. m = 32.3 g. The change in temperature is given here. Δt = 3.5°C. Step 2: Plug in these values into the heat equation and solve for the unknown value. Q = m x C x Δt. C = Q/ (m x Δt) WebTo calculate the total heat we added, we use the formula, Q=mCpΔT. In our equation, Q is heat energy, m is the ice's mass, Cp is the specific heat capacity, ΔT is the temperature change. Let's calculate our heat energy if we started with 100.0 grams of ice. We look up the specific heat capacity. For ice, it's 2.03JgoC. headers are 1.10.5 library is 1.10.6WebIn the equation, you only need to put the change in degrees C or the change in degrees K not the actual temperature itself.
