1. Convert the following temperatures to their values in c~tinuance the Fahrenheit and Kelvin scales: (a) the ebullition point of liquid hydrogen, –252.87°C (b) the degree of heat of a room at 20°C.
2. A resolute-volume gas thermometer is calibrated in sly ice (–80.0°C) and in boiling ethyl alcohol (78.0°C). The respective pressures are 0.900 atm and 1.635 atm. (a) What precise signification of absolute zero does the calibration yield? (b) What pressures would have existence found at the freezing and boiling points of water? (Note that we be delivered of the linear relationship P = A + BTc, at what place A and B are constants.)
3. The affecting point of gold is 1 064°C, and the boiling point is 2 660°C. (a) Express these temperatures in Kelvins. (b) Compute the schism of the two temperatures in Celsius degrees and in Kelvins.
4. A cylindrical front sleeve is to be shrink-fitted transversely a brass shaft whose diameter is 3.212 cm at 0°C. The diameter of the sleeve is 3.196 cm at 0°C. (a) To that which temperature must the sleeve be heated previous to it will slip over the missile?

TUTORIAL 1
1. Convert the following temperatures to their values forward the Fahrenheit and Kelvin scales: (a) the
boiling point of liquid hydrogen, –252.87°C (b) the temperature of a room at 20°C.
2. A continuous-volume gas thermometer is calibrated in exsiccate ice (–80.0°C) and in boiling ethyl
alcohol (78.0°C). The own pressures are 0.900 atm and 1.635 atm. (a) What precise signification of
absolute zero does the calibration yield? (b) What pressures would exist found at the freezing and
ebullition points of water? (Note that we gain the linear relationship P = A + BTc, to which place A and B
are constants.)
3. The inteneration point of gold is 1 064°C, and the ebullition point is 2 660°C. (a) Express these
temperatures in Kelvins. (b) Compute the bickering of the two temperatures in Celsius degrees
and in Kelvins.
4. A cylindrical presumption sleeve is to be shrink-fitted excessively a brass shaft whose diameter is 3.212 cm
at 0°C. The distance through the centre of the sleeve is 3.196 cm at 0°C. (a) To the sort of temperature must the sleeve
be heated in the van of it will slip over the arrow? (b) Alternatively, to what temperature must the
shaft be cooled before it resolution slip into the sleeve?
5. A third power of solid aluminum has a power of 1.00 m3 at 20°C. What degree of heat change is
required to produce a 100-cm3 become greater in the volume of the raise to the third power?
6. A gold ring has one inner diameter of 2.168 cm at a degree of heat of 15.0°C. Determine its interior
diameter at 100°C (gold = 1.42 10–5 °C–1).
7. The Trans-Alaskan pipeline is 1 300 km in extent, reaching from Prudhoe Bay to the harbor of
Valdez, and is subject to temperatures ranging from –73°C to +35°C. How much does the steel
pipeline expand exactly to the difference in temperature?
8. (a) An complete gas occupies a volume of 1.0 cm3 at 20°C and of the atmosphere pressure. Determine
the number of molecules of elastic fluid in the container. (b) If the distress of the 1.0-cm3 bulk is
reduced to 1.0 10–11 Pa (every extremely good vacuum) while the temperature remains constant,
how many moles of gas remain in the container?
9. A cylinder through a movable piston contains gas at a degree of heat of 27.0°C, a volume of 1.50 m3,
and each absolute pressure of 0.200 105 Pa. What choose be its final temperature if the gas is
compressed to 0.700 m3 and the unconditioned pressure increases to 0.800 105 Pa?
10. What is the average kinetic energy of a molecule of oxygen at a degree of heat of 300 K?
