Evaluate the heat transferred to the surroundings : Assuming the mixture has the same specific heat (4.184J/goC) and density (1.00 g/cm3 or 1.00 g/mL) as water, calculate the heat (in J) transferred to the surroundings, qsurr.

Find how much current is flowing on the secondary side : Assume that a given transformer is 100% efficient; that is, the power being supplied by the primary side is transported without loss to the secondary side. (Transformers are not 100% efficient. One can detect this by the heat that they radiate.)
