Question
Chapter 14, Problem 5QAP
To determine
The parts of careful physics student's idea that are valid and the parts that are not if she is reading about the concept of temperature and has what she thinks is a bright idea, while reading the text, she discovers that the Celsius temperature scale and the Kelvin temperature scale both have the same increments for equal temperature differences. However, the Fahrenheit scale was described as having larger increments for the same temperature differences, from this information the student determines that Celsius (or Kelvin) thermometers will always be shorter than Fahrenheit thermometers.

The temperature difference between the hot and cold fluids in a heat exchanger is given to be DT1 at one end and DT2 at the other end. Can the logarithmic temperature difference DTlm of this heat exchanger be greater than both DT1 and DT2? Explain.
Hi! I have a question.
Unsatisfied with the Celsius and Fahrenheit temperature scales, you decide to create your own. On your temperature scale, the ice point is 77°M and the steam point is at 437°M, where "°M" stands for "my scale." What temperature on your scale corresponds to 68°F?
(A) 154°M, (B) 168°M, (C) 140°M, (D) 136°M, (E) 149°MMy answer below, is this correct?68°F = (E) 149°M
Two variables are proportional if they can be written at y kx = , where k is some constant. This leads to the fact that when x = 0 then y = 0 as well. Is the temperature measured in Celsius proportional to the temperature measured in Fahrenheit? Explain.

- Can you determine the temperature of a vacuum? Explainarrow_forwardDuring the summer after your first year at Carnegie Mellon, you are lucky enough to get a job making coffee at Starbucks, but you tell your parents and friends that you have secured a lucrative position as a "java engineer." An eccentric chemistry professor (not mentioning any names) stops in every day and orders 200ml of Sumatran coffee at precisely 70.0°C. You then need to add enough milk at 5.00°C to drop the temperature of the coffee, initially at 80.0°C, to the ordered temperature. Calculate the amount of milk (in ml) you must add to reach this temperature. Show all your work in the provided spaces. In order to simplify the calculations, you will start by assuming that milk and coffee have the specific heat and density as if water. In the following parts, you will remove these simplifications. Solve now this problem assuming the density is 1.000 g/ml for milk and coffee and their specific heat capacity is 4.184 J/(g ºC).arrow_forwardTwo finned surfaces are identical, except that the convection heat transfer coefficient of one of them is twice that of the other. For which finned surface is the (a) fin effectiveness and (b) fin efficiency higher? Explain.arrow_forward
- At our distance from the Sun, the intensity of solar radiation is 1 370 W/m2. The temperature of the Earth is affected by the greenhouse effect of the atmosphere. This phenomenon describes the effect of absorption of infrared light emitted by the surface so as to make the surface temperature of the Earth higher than if it were airless. For comparison, consider a spherical object of radius r with no atmosphere at the same distance from the Sun as the Earth. Assume its emissivity is the same for all kinds of electromagnetic waves and its temperature is uniform over its surface. (a) Explain why the projected area over which it absorbs sunlight is r2 and the surface area over which it radiates is 4r2. (b) Compute its steady-state temperature. Is it chilly?arrow_forwardStars A and B have the same temperature, but star A has twice the radius of star B. (a) What is the ratio of star As power output to star Bs output due to electromagnetic radiation? The emissivity of both stars can be assumed to be 1. (b) Repeat the question if the stars have the same radius, but star A has twice the absolute temperature of star B. (c) Whats the ratio if star A has both twice the radius and twice the absolute temperature of star B?arrow_forwardCompare the SI units of specific heat and latent heat and explain any differences.arrow_forward
- Stars A and B have the same temperature, but star A has twice the radius of star B. (a) What is the ratio of star As power output to star Bs output due to electromagnetic radiation? The emissivity of both stars can be assumed to be 1. (b) Repeat the question if the stars have the same radius, but star A has twice the absolute temperature of star B. (c) Whats the ratio if star A has both twice the radius and twice the absolute temperature of star B?arrow_forwardIn 1993, the U.S. government instituted a requirement that all room air conditioners sold in the United States must have an energy efficiency ratio (EER) of 10 or higher. The EER is defined as the ratio of the cooling capacity of the air conditioner, measured in British thermal units per hour, or Btu/h, to its electrical power requirement in watts. (a) Convert the EER of 10.0 to dimensionless form, using the conversion 1 Btu = 1 055 J. (b) What is the appropriate name for this dimensionless quantity? (c) In the 1970s, it was common to find room air conditioners with EERs of 5 or lower. State how the operating costs compare for 10 000-Btu/h air conditioners with EERs of 5.00 and 10.0. Assume each air conditioner operates for 1 500 h during the summer in a city where electricity costs 17.0 per kWh.arrow_forward
