Chapter 1, Problem 1.44E

Titanium metal is used in aerospace alloys to add strength and corrosion resistance. Titanium melts at 1677C. What is this temperature in degrees Fahrenheit?

The temperature on the surface of the Sun is 5.5 103 C. What is this temperature in kelvins?

1-86 The specific heats of some elements at 25oC are as follows: aluminum = 0.215 cal/g · oC; carbon (graphite) = 0.170 caI/g oC; iron = 0.107 cal/g mercury = 0.033 1 caI/g oC. (a) Which element would require the smallest amount of heat to raise the temperature of 100 g of the element by 10oC? (b) If the same amount of heat needed to raise the temperature of 1 g of aluminum by 25oC were applied to 1 g of mercury, by how many degrees would its temperature be raised? (c) If a certain amount of heat is used to raise the temperature of 1.6 g of iron by 10oC, the temperature of 1 g of which element would also be raised by 10oC, using the same amount of heat?

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

Convert the following Fahrenheit temperatures to Celsius degrees. a chilly morning ¡n early autumn. 45 °F a hot, dry day in the Arizona desert. 115 °F the temperature in winter when my car won’t start, 10°F the surface of a star, 10,000°F

A friend tells you that it is 69. 1 °F outside. What is this temperature in Celsius?

The melting point of sodium chloride, table salt, is 801 C. What is this temperature in degrees Fahrenheit and in kelvins?

Calcium carbonate, a white powder used in toothpastes, antacids, and other preparations, decomposes when heated to about 825C. What is this temperature in degrees Fahrenheit?

On the planet Xgnu, the natives have 14 fingers. On the official Xgnuese temperature scale (CX), the boiling point of water (under an atmospheric pressure similar to earth’s) is 140 °X, whereas water freezes at 14 CX. Derive the relationship between °X and °C.
