Chapter 1: Problem 55

Convert the following Celsius temperatures to Kelvin and to Fahrenheit degrees. a. the temperature of someone with a fever, \(39.2^{\circ} \mathrm{C}\) b. a cold wintery day, \(-25^{\circ} \mathrm{C}\) c. the lowest possible temperature, \(-273^{\circ} \mathrm{C}\) d. the melting-point temperature of sodium chloride, \(801^{\circ} \mathrm{C}\)

Short Answer

Expert verified
a. Fever Temperature: 312.35 K and 102.56 掳F b. Cold Wintery Day Temperature: 248.15 K and -13 掳F c. Lowest Possible Temperature: 0.15 K and -459.4 掳F d. Melting-point Temperature of Sodium Chloride: 1074.15 K and 1473.8 掳F

Step by step solution

01

a. Fever Temperature

Given Celsius temperature: \(39.2^{\circ} \mathrm{C}\) Celsius to Kelvin: K = C + 273.15 K = 39.2 + 273.15 K = 312.35 K Celsius to Fahrenheit: F = (9/5 * C) + 32 F = (9/5 * 39.2) + 32 F = 102.56 掳F Therefore, the fever temperature is 312.35 K and 102.56 掳F.
02

b. Cold Wintery Day Temperature

Given Celsius temperature: \(-25^{\circ} \mathrm{C}\) Celsius to Kelvin: K = C + 273.15 K = -25 + 273.15 K = 248.15 K Celsius to Fahrenheit: F = (9/5 * C) + 32 F = (9/5 * -25) + 32 F = -13 掳F Therefore, the cold wintery day temperature is 248.15 K and -13 掳F.
03

c. Lowest Possible Temperature

Given Celsius temperature: \(-273^{\circ} \mathrm{C}\) Celsius to Kelvin: K = C + 273.15 K = -273 + 273.15 K = 0.15 K Celsius to Fahrenheit: F = (9/5 * C) + 32 F = (9/5 * -273) + 32 F = -459.4 掳F Therefore, the lowest possible temperature is 0.15 K and -459.4 掳F.
04

d. Melting-point Temperature of Sodium Chloride

Given Celsius temperature: \(801^{\circ} \mathrm{C}\) Celsius to Kelvin: K = C + 273.15 K = 801 + 273.15 K = 1074.15 K Celsius to Fahrenheit: F = (9/5 * C) + 32 F = (9/5 * 801) + 32 F = 1473.8 掳F Therefore, the melting-point temperature of sodium chloride is 1074.15 K and 1473.8 掳F.

Ethylene glycol is the main component in automobile antifreeze. To monitor the temperature of an auto cooling system, you intend to use a meter that reads from 0 to 100 . You devise a new temperature scale based on the approximate melting and boiling points of a typical antifreeze solution \(\left(-45^{\circ} \mathrm{C}\right.\) and \(\left.115^{\circ} \mathrm{C}\right)\). You wish these points to correspond to \(0^{\circ} \mathrm{A}\) and \(100^{\circ} \mathrm{A}\), respectively. a. Derive an expression for converting between \({ }^{\circ} \mathrm{A}\) and \({ }^{\circ} \mathrm{C}\). b. Derive an expression for converting between \({ }^{\circ} \mathrm{F}\) and \({ }^{\circ} \mathrm{A}\). c. At what temperature would your thermometer and a Celsius thermometer give the same numerical reading? d. Your thermometer reads \(86^{\circ} \mathrm{A} .\) What is the temperature in \({ }^{\circ} \mathrm{C}\) and in \({ }^{\circ} \mathrm{F}\) ? e. What is a temperature of \(45^{\circ} \mathrm{C}\) in \({ }^{\circ} \mathrm{A}\) ?

When a marble is dropped into a beaker of water, it sinks to the bottom. Which of the following is the best explanation? a. The surface area of the marble is not large enough to be held up by the surface tension of the water. b. The mass of the marble is greater than that of the water. c. The marble weighs more than an equivalent volume of the water. d. The force from dropping the marble breaks the surface tension of the water. e. The marble has greater mass and volume than the water. Justify your choice, and for choices you did not pick, explain what is wrong about them.

How many significant figures are in each of the following? a. 100 e. \(0.0048\) b. \(1.0 \times 10^{2}\) f. \(0.00480\) c. \(1.00 \times 10^{3}\) g. \(4.80 \times 10^{-3}\) d. 100 . h. \(4.800 \times 10^{-3}\)

A rule of thumb in designing experiments is to avoid using a result that is the small difference between two large measured quantities. In terms of uncertainties in measurement, why is this good advice?
