An electric coffeemaker has a 610-W heating element. The specific heat of water is 4.19 × 103 J/(kg⋅°C). How long, in seconds, does it take the coffeemaker to heat 0.76 L of water from 18°C to 88°C, assuming all the heat produced by the heating element goes into the water?
A baking dish is removed from a hot oven and placed on a cooling rack. As the dish cools down to 31.0°C from 189°C, its net radiant power decreases to 13.0 W. What was the net radiant power of the baking dish when it was first removed from the oven? Assume that the temperature in the kitchen remains at 24.0°C as the dish cools.
