(b) Is your result consistent with the large cooling towers used by many large electrical power plants?arrow_forwardThe Sun radiates energy at the rate of 3.801026W from its 5500C surface into dark empty space (a negligible fraction radiates onto Earth and the other planets). The effective temperature of deep space is 270C. (a) What is the increase in entropy in one day due to this heat transfer? (b) How much work is made unavailable?arrow_forwardA person inhales and exhales 2.00 L of 37.0C air, evaporating 4.00102g of water from the lungs and breathing passages with each breath.

(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_forward
- Assume you are measuring the specific heat of a sample of originally hot metal by using a calorimeter containing water. Because your calorimeter is not perfectly insulating, energy can transfer by heat between the contents of the calorimeter and the room. To obtain the most accurate result for the specific heat of the metal, you should use water with which initial temperature? (a) slightly lower than room temperature (b) the same as room temperature (c) slightly higher than room temperature (d) whatever you like because the initial temperature makes no differencearrow_forwardA bag containing 0C ice is much more effective in absorbing energy than one containing the same amount at 0C water. a. How much heat transfer is necessary to raise the temperature of 0.800 kg of water from 0C to 30.0C ? b. How much heat transfer is required to first melt 0.800 kg of 0C ice and then raise its temperature? c. Explain how your answer supports the contention that the ice is more effective.arrow_forwardA sample of a diatomic ideal gas has pressure P and volume V. When the gas is warmed, its pressure triples and its volume doubles. This warming process includes two steps, the first at constant pressure and the second at constant volume. Determine the amount of energy transferred to the gas by heat.arrow_forward
- Unreasonable Results (a) Calculate the rate of heat transfer by conduction through a window with an area of 1.00 m2 that is 0.750 cm thick, if its inner surface is at 22.00C and its outer surface is at 35.00C (b) What is unreasonable about this result? (c) Which premise or assumption is responsible?arrow_forwardUnreasonable Results (a) An automobile mechanic claims that an aluminum rod fits loosely into its hole on an aluminum engine block because the engine is hot and the rod is cold.

(2) Which premise is responsible?arrow_forwardUnreasonable Results Suppose the relative humidity is 80% on a day when the temperature is 30.0C.

(b) What gauge pressure does this correspond to?arrow_forwardWhat does it mean to say that two systems are in thermal equilibrium?arrow_forwardA sample of gas with a thermometer immersed in the gas is held over a hot plate. A student is asked to give a step-by-step account of what makes our observation of the temperature of the gas increase. His response includes the following steps, (a) The molecules speed up. (b) Then the molecules collide with one another more often. (c) Internal friction makes the collisions inelastic, (d) Heat is produced in the collisions. (e) The molecules of the gas transfer more energy to the thermometer when they strike it, so we observe that the temperature has gone up.
