WebDuring cooking, heat is transferred from the source of heat to the food through conduction (e.g. grilling steak on a grilling pan sitting on a stove), convection (e.g. running cold water over frozen food to speed up thawing process) and/or radiation (roasting marshmallow over fire). WebSuppose that a moderately-sized house has inside dimensions 12.0m×18.0m×3.00m high, and that all air is replaced in 30.0 min. Calculate the heat transfer per unit time in watts needed to warm the incoming cold air by 10.0 ºC, thus replacing the heat transferred by convection alone. Strategy: Heat is used to raise the temperature of air so that
