3. The yellow propane-powered snow melter has been working hard on campus this winter. (a) If the full accumulation of this years' snowfall on king's College Circle was plowed into a pile and then melted. How much energy would be required for the melting? [assume propane-fired melting is 100% efficient] (b) If the full accumulation of this year's snowfall on all Metropolitan Toronto city streets and highways was similarly melted, how much energy would be required [in MTOE]? (c) Estimate the additional increase in each Torontonian's carbon footprint, if we did (b). 3. The yellow propane-powered snow melter has been working hard on campus this winter.
