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.
A classroom has dimensions 8.00 m x 10.00 m x 3.00 m. A 1000 W electric space

the density of air is 1.29 kg/m°, and the specific heat capacity of air is 1004 J/(kg-K),
how long will it take to heat the room? Assume no loss of thermal energy to the
surroundings.
A) 1.30 minutes

A family comes home from a long vacation with laundry to do and showers to take. The water heater has been turned off during vacation. If the water heater has a capacity of 51.3 gallons and a 4940 W heating element, how much time is required to raise the temperature of the water from 19.4°C to 63.3°C? Assume that the heater is well insulated and no water is withdrawn from the tank during this time.
