The average thermal conductivity of the walls (including windows) and roof of a house in the figure shown below is 4.8 10-4 kW/m · °C, and their average thickness is 20.8 cm. The house is heated with natural gas, with a heat of combustion (energy given off per cubic meter of gas burned) of 9,300 kcal/m3. How many cubic meters of gas must be burned each day to maintain an inside temperature of 25.9°C if the outside temperature is 0.0°C? Disregard surface air layers, radiation, and energy loss by heat through the ground. m3 A house has a rectangular base and a roof that peaks along a line above the center of the house and parallel to the length of the house. This roof slopes downward from the peak to each edge at an angle of 37.0° with the horizontal. The length of the front of the house is 10.0 meters. The width of the house is 8.00 meters. The height from the front of the house up to the edge of the roof is 5.00 meters.

A chunk of metal with a mass of 85.0 grams and a specific heat of 759 joules per kilogram·kelvin is heated to 78.9 degrees Celsius and placed in 122 milliliters of water (c = 4186 J/kg·K) at 18.6 degrees Celsius. What is the final temperature of the metal and water? Hint: The heat lost by the metal is gained by the water, so the sum of the heats is zero.
A hot steel plate with a surface area of 2.17 m2 and a constant surface temperature of 165°C is exposed to ambient air at 24°C. If the convection heat transfer coefficient is 15.4 W/m2· K, what is the rate of heat transfer (in W) from the plate to the air [round your final answer to zero decimal places]?
On a sunny day when the outside temperature is 34.0°C, a car parked in the sun is receiving 812 watts/m2 of incoming solar radiation (Insolation). Because the car radiates heat off of a greater surface area, the car in-turn radiates off heat at a rate of 169 watts/m². If the car is considered a perfect absorber and emitter of radiative energy, what will the equilibrium temperature inside the car be? °C
