Consider a room that is initially at the outdoor temperature of 20 C. The room contains a 60-W light bulb, a 3000-W electric oven, a 400-W TV set and two 300-W fridge. Assuming no heat transfer through the walls, determine the rate of increase of the energy content of the room when all of these electric devices are on.

(a) What is the rate of heat conduction through the 3.00-cm-thick fur of a large animal having a I .40-m surface area? Assume that the animal's skin temperature is 32.0 , that the air temperature is 5.00 , and that has the same thermal conductivity as air. (b) What food intake will the animal need in one day to replace this heat transfer?
Consider a room that is initially at the outdoor temperature of 20°C. The room contains a 40-W lightbulb, a 110-W TV set, a 300-W refrigerator, and a 1200-W iron. Assuming no heat transfer through the walls, determine the rate of increase of the energy content of the room when all of these electric devices are on.
A 56 kW electric furnace measures 1.2m x 1.3m x 0.7m. When the temperature inside the furnace is 1613 ºC, a block of aluminum with a mass of 283 kg and a temperature of 18 ºC is placed inside. Assuming the heat loss from the furnace walls is 529 W/m, how long (in min) will it take to heat the block to the furnace temperature? (Specific heat of aluminum is 0.90 kJ/kg. K)
How much work must be done by this heat pump to supply 2550 J of heat on a day when the outside temperature is 253 K?
Consider an opaque plate that is well insulated on the edges and it is heated at the bottom with an electric heater. The plate has an emissivity of 0.67, and is situated in an ambient surrounding temperature of 7°C where the natural convection heat transfer coefficient is 7 W/m2?K. To maintain a surface temperature of 80°C, the electric heater supplies 1000 W/m2 of uniform heat flux to the plate. Determine the radiosity of the plate under these conditions.
To help keep his barn warm on cold days, a farmer stores 860 kg of solar-heated water (Lf = 3.35E+5 J/kg) in barrels. For how many hours would a 1.89 kW electric space heater have to operate to provide the same amount of heat as the water does, when it cools from 11.8 to 0∘∘C and completely freezes?
In the heating seasons the heat loss from a building (and thus the heating cost) is strongly dependent on the difference between the indoor and outdoor temperature. If the average outdoor temperature in a particular city during the heating season is 45 F (7 C), what is the effect on heating cost percentage-wise if the thermostat setting is fixed at 74 F (23.3 F) instead of 68 F (20 C)?
What is the change in internal energy of a system which does 4.50 X 105 J of work while 3.00 X 106 J of heat transfer occurs in a system, and 8.00 X 106 J of heat transfers to the environment?
The ground temperature a few meters below the surface is fairly constant throughout the year and is near the average value of the air temperature. In areas in which the air temperature drops very low in the winter, the exterior unit of a heat pump designed for heating is sometimes buried underground in order to use the earth as a thermal reservoir. Why is it worthwhile to bury the heat exchanger, even if the underground unit costs more to purchaseand install than one above ground?
A well-sealed room contains 60 kg of air at 200 kPa and 25°C. Now solar energy enters the room at an average rate of 0.8 kJ/s while a 120-W fan is turned on to circulate the air in the room. If heat transfer through the walls is negligible, the air temperature in the room in 30 min will be
A Styrofoam container used as a picnic cooler contains a block of ice at 0 oC. If 0.5 kg of ice melts in 0.79 hours, how much heat energy per second is passing through the walls of the container (in Watts)?
