(a) How much heat transfer occurs due to evaporation in each breath? (b) What is the rate of heat transfer in watts if the person is breathing at a moderate rate of 18.0 breaths per minute? (c) If the inhaled air had a temperature of 20.0C, what is the rate of heat transfer for warming the air? (d) Discuss the total rate of heat transfer as it relates to typical metabolic rates. Will this breathing be a major form of heat transfer for this person?arrow_forwardReview. A house has well-insulated walls. It contains a volume of 100 m3 of air at 300 K. (a) Calculate the energy required to increase the temperature of this diatomic ideal gas by 1.00C. (b) What If? If all this energy could be used to lift an object of mass m through a height of 2.00 m, what is the value of m?arrow_forwardA large body of lava from a volcano has stopped flowing and is slowly cooling. The interior of the lava is at 1200C, its surface is at 450C, and the surroundings are at 27.0C. (a) Calculate the rate at which energy is transferred by radiation from 1.00m2 of surface lava into the surroundings, assuming the emissivity is 1.00. (b) Suppose heat conduction to the surface occurs at the same rate. What is the thickness of the lava between the 450C surface and the 1200C interior, assuming that the lava’s conductivity is the same as that of brick?arrow_forward
- What does it mean to say that two systems are in thermal equilibrium?arrow_forwardHow is heat transfer related to temperature?arrow_forwardEven when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150 MW by the radioactive decay of fission products. This heat transfer causes a rapid increase in temperature it the cooling system fails (1 watt 2 1 joule/second or 1W=1J/s and 1MW=1megawatt ). (a) Calculate the rate of temperature increase in degrees Celsius per second (C/s) if the mass of the reactor core is 1.60105kg and it has an average specific heat of 0.3349kJ/kgC. (b) How long would it take to obtain a temperature increase of 2000C, which could cause some metals holding the radioactive materials to melt? (The initial rate of temperature increase would be greater than that calculated here because the heat transfer is concentrated in a smaller mass. Later, however, the temperature increase would slow down because the 5105-kg steel containment vessel would also begin to heat up.) Figure 14.32 Radioactive spentfuel pool at a nuclear power plant.

He receives radiation at the rate of 20.0 W—half what you would calculate if the entire region behind him was hot. The rest of the surroundings are at 34.0C.
