1. 

To the
nearest degree, what is absolute zero on the Celsius scale? 


2. 

To the
nearest degree, if room temperature is 65^{o}F what is it in ^{o}C? Multiply by 5/9 not 9/5. Review Section 132 in Giancoli. 


3. 

To the
nearest degree, if it is hot outside at 100^{o}F what is it in ^{o}C? Review Section 132 in Giancoli. 


4. 

What is
40^{o}C on the Fahrenheit scale? You must add 32. Review Section 132 in Giancoli. 


5. 

To the
nearest degree, what is absolute zero on the Fahrenheit scale? You must add 32. Review Section 132 in Giancoli. 


6. 

The
Rankine temperature scale bears the same relationship to the Fahrenheit scale
as the Kelvin does to the Celsius. To the nearest degree, what is the
freezing point in Rankine? This would be the boiling point. Review Section 137 in Giancoli. 


7. 

Temperature
one is 10^{o}C and the second temperature is 30^{o}C. What is
the average temperature in Kelvin? This is the lower temperature. Review Section 137 in Giancoli. 


8. 

What is
the difference in C^{o} of the two temperatures, 35^{o}F and
62^{o}F? It is (5/9) of the difference in Fahrenheit. Review Section 132 in Giancoli. 


9. 

If the
temperature difference in Celsius is 50^{o}C, what is the difference
in Fahrenheit? Use (9/5) not (5/9). Review Section 132 in Giancoli. 


10. 

Which of
the following temperatures is the highest? This is 10.2^{o}C. Review Section 132 and 137 in Giancoli. 


11. 

The coefficient
of thermal (linear) expansion,a, for aluminum is 25x10^{6}(C^{o})^{1}.
What is the change in length of a 1 meter bar if the temperature increases 30
C^{o}? Review Section 134 in Giancoli. 


12. 

The
coefficient of thermal expansion for iron is 12x10^{6}(C^{o})^{1}.
Which will expand more as temperature increases, a 2 meter iron bar or a 1
meter aluminum bar? Review Section 134 in Giancoli. 


13. 

A 1 meter
diameter hole is cut into a aluminum sheet and the temperature is increased
by 100 C^{o}. What is the new diameter of the hole? It increases in size. Review Section 134 in Giancoli. 


14. 

An
aluminum hollow metal sphere with a radius of 1 meter is exposed to a 200 F^{o}
temperature increase. What is the ratio of the new volume to the old one? Review Example 137 in Giancoli. 


15. 

The
coefficient of volume expansion, beta, for Pyrex is 9x10^{6}(C^{o})^{1}
and the coefficient of thermal expansion, alpha, for ethyl alcohol is 1100x10^{6}(C^{o})^{1}.
If the alcohol fills 50% of a Pyrex bottle what % will it occupy if the
temperature is increased by 30 C^{o}? Review Example 137 in Giancoli. 


16. 

If 10
moles of a gas has a gauge pressure of 2 atm and a temperature of 200 K, what
is its volume? You must convert to absolute pressure in Pa. Review Example 138 in Giancoli. 


17. 

10 moles
of a gas has a gauge pressure of 2 atm and a temperature of 200 K. If the
temperature is doubled, what will be the new gauge pressure in atm? This is the new absolute pressure. Review Example 1313 in Giancoli. 


18. 

10 moles
of a gas has a gauge pressure of 2 atm and a temperature of 200 K. If the
volume of the gas is doubled and the gauge pressure dropped in half (1 atm),
what is the new temperature? Review Section 139 in Giancoli. 


19. 

10 moles
of a gas has a gauge pressure of 2 atm and a temperature of 200 K. How many
molecules are there in the gas? 


20. 

10 moles
of a gas has a gauge pressure of 2 atm and a temperature of 200 K. If the
molecules are hydrogen (atomic mass =1.008 u), what is the mass of the gas? A mole is based on grams. Review Section 1310 in Giancoli. 


21. 

If
temperature is measured in J/molecule (which is what it measures) instead of
kelvin, what would be the value of k, Boltzmann's constant? This is the normal value. Review Section 1311 in Giancoli. 


22. 

If
temperature is measured in J/molecule (which is what it measures) instead of
kelvin and if we call the temperature scale the G scale what would be the
temperature of the freezing point of water? 


23. 

What would
be the conversion between the G scale (question 22) and the Celsius scale. 


24. 

Six
molecules have the speeds (in arbitrary units) of 2, 2, 4, 8, 4, 10. What is
their average speed? Add and divide by 6. Review Section 1311 in Giancoli. 


25. 

Six
molecules have the speeds (in arbitrary units) of 2, 2, 4, 8, 4, 10. What is
the rms speed (to the nearest unit) of the molecules? Take the average of the squared numbers and then tahe the squareroot. Review Section 1311 in Giancoli.
