1. A constant-volume gas thermometer is calibrated in dry ice (that is, evaporating
carbon dioxide in the solid state, with a temperature of –80.0°C) and in boiling ethyl
alcohol (78.0°C). The two pressures are 0.900 atm and 1.635 atm, respectively. (a) What
Celsius value of absolute zero does the calibration yield? What is the pressure at (b)
the freezing point of water and (c) the boiling point of water?
T = −273°C
2. Convert the following to equivalent temperatures on the Celsius and Kelvin scales:
(a) the normal human body temperature, 98.6°F; (b) the air temperature on a cold day,
3. Liquid nitrogen has a boiling point of –195.81°C at atmospheric pressure. Express
this temperature in (a) degrees Fahrenheit and (b) kelvins.
4. The temperature difference between the inside and the outside of an automobile
engine is 450°C. Express this temperature difference on (a) the Fahrenheit scale and
(b) the Kelvin scale.

5. The Trans-Alaska pipeline is 1 300 km long, reaching from Prudhoe Bay to the port
of Valdez. It experiences temperatures from –73°C to +35°C. How much does the steel
pipeline expand because of the difference in temperature? How can this expansion be
6. A pair of eyeglass frames is made of epoxy plastic. At room temperature (20.0°C),
the frames have circular lens holes 2.20 cm in radius. To what temperature must the
frames be heated if lenses 2.21 cm in radius are to be inserted in them? The average
coefficient of linear expansion for epoxy is 1.30 × 10–4 (°C)–1.
7. Each year thousands of children are badly burned by hot tap water. Figure P16.7
shows a cross-sectional view of an antiscalding faucet attachment designed to prevent
such accidents. Within the device, a spring made of material with a high coefficient of
thermal expansion controls a movable plunger. When the water temperature ris
