36. GO A copper pipe with an outer radius of 0.013 m runs from anoutdoor wall faucet into the interior of a house. The temperature of thefaucet is 4.0 °C, and the temperature of the pipe, at 3.0 m from the faucet,is 25 °C. In fifteen minutes, the pipe conducts a total of 270 J of heat tothe outdoor faucet from the house interior. Find the inner radius of thepipe. Ignore any water inside the pipe.

When the indoor temperature of a house is 25°C and the outdoor temperature is -8°C, the inside and outside surfaces of the glass are measured to be 21.3°C and 17.3°C. If the glass has an area of 3.16 m2 and a thickness of 6.14 mm, what is the rate of heat (in W) lost though the window? {kglass = 0.78 W/m∙K}
3. A 3.2 m length of copper pipe extends directly from a hot-water heater in a basement to a faucet on the first floor of a house. If the faucet isn't fixed in place, how much will it rise when the pipe is heated from 20.0° C to 85.9° C. The coefficient of linear expansion for copper is 1.6*10-5 K−1.
The rate of heat transfer on a cold day in the Canada through a rectangular window is 2336 W. The temperature inside the home is 20.2 °C and the temperature outside the home is -7 °C. What is the area of the room if the thickness 6.7 mm and thermal conductivity value of 0.25 W/m/°C?
When heating water for cooking food, it is common to use an electric or natural-gas cooktop. A metal pot with radius r=0.11m is filled with water to a depth of h=0.16m and heated on such a cooktop. The water is initially at a temperature of T0=25∘C. a. Enter an expression for the amount of heat required to raise the temperature of the water to its boiling point of Tv=100∘C in terms of r, h, T0, Tv, ρ and c. b. Calculate the amount of heat, in joules, required to raise the temperature of the water to its boiling point. Water has a density of ρ=1.000×103kg/m3 and a specific heat of c=4.186×103J/(kg⋅∘C) c. According to the U.S. Energy Information Administration, the average cost of electricity in the U.S. is about $0.10 per kilowatt-hour, or $0.028 per megajoule of electrical energy. Assuming all the electrical energy goes into heating the water on the cooktop, how much does it cost, in dollars, to heat the pot of water with electricity? Ignore the heat required to raise the temperature…
A thermos contains 160 cm3 of coffee at 93.2 °C. To cool the coffee, you drop two 10.5-g ice cubes into the thermos. The ice cubes are initially at 0 °C and melt completely. What is the final temperature of the coffee in degrees Celsius? Treat the coffee as if it were water.
