In winter, a canal in Canada has an ice layer on its surface. The depth from the surface to the bottom of the canal is 2.2m. If the temperature of the air above the ice is-5.4 °C and the temperature of water at the bottom of the canal is 3.9 °C, what would be the thickness of the ice layer? (Please write your answer in the box without rounding. Write what you see on the calculator up to two decimal points WITHOUT UNIT.)
Suppose a walrus transfers energy by conduction through its blubber at the rate of 125 W when immersed in -1.25°C water. The walrus’s internal core temperature is 37.0°C, and it has a surface area of 1.85 m2. Chart attached. What is the average thickness of its blubber, in centimeters, which has the conductivity of fatty tissue?
When you turn your hot water on in the shower, it takes a bit for the water to get warm. Some of this is because the water in the pipe is cold but some of it is because the water from the hot water heater must heat the copper plumbing pipe itself. Copper has a specific heat of 0.39R. How much energy does it take to heat 2 kilograms of copper pipe from 70°F to 130°F? Report your answer in Joules. (Hint: Note that you'll need to convert kJ to J and F to K.)
Bebang owns a 130-mm-thick concrete brick table top that has an area of 10,000,000 mm^2 and a 0.750 cm thick glass plate that has an area of 20,000 cm^2. Assuming the same temperature difference across each, what is the ratio of the rate of heat conduction through the plate with respect to the rate of heat conduction through the table top? Use Table 10.1 (given below) for the value of Thermal Conductivity.
