Final answer. Step 1/2. To calculate the magnitude of heat transfer required to cool the liquid mixture, we can use the following formula: Q = m C Δ T Where Q is the heat transfer, m is the mass of the mixture, C is the specific heat capacity, and ΔT is the temperature change. First, we need to find the mass of the liquid mixture.
