2. ConcepTest 16.1 Degrees A) one Celsius degree B) one Kelvin degree
C) one Fahrenheit degree
D) both one Celsius degree and one Kelvin degree
E) both one Fahrenheit degree and one Celsius degree
Which is the largest unit: one Celsius degree, one Kelvin degree, or one Fahrenheit degree?

3. ConcepTest 16.2 Freezing Cold
A) yes, at 0 °C
B) yes, at -273 °C
C) yes, at 0 K
D) no
It turns out that – 40°C is the same temperature as – 40°F. Is there a temperature at which the Kelvin and Celsius scales agree?

4. ConcepTest 16.3 Thermometers
A) the mercury contracts before the glass contracts
B) the glass contracts before the mercury contracts
C) the mercury contracts before the glass expands
D) the glass expands before the mercury expands
E) the mercury expands before the glass contracts
You may notice that if a mercury-in-glass thermometer is inserted into a hot liquid, the mercury column first drops, and then later starts to rise (as you expect). How do you explain this drop?

5. ConcepTest 16.4 Glasses
A) run hot water over them both
B) put hot water in the inner one
C) run hot water over the outer one
D) run cold water over them both
E) break the glasses
Two drinking glasses are stuck, one inside the other. How would you get them unstuck?

6. ConcepTest 16.5 Steel Expansion II
Metals such as brass expand when heated. The thin brass plate in the movie has a circular hole in its center. When the plate is heated, what will happen to the hole?
A) gets larger
B) gets smaller
C) stays the same
D) vanishes

7. ConcepTest 16.6 Thermal Contact I
Two objects are made of the same material, but have different masses and temperatures. If the objects are brought into thermal contact, which one will have the greater temperature change?
A) the one with the higher initial temperature
B) the one with the lower initial temperature
C) the one with the greater mass
D) the one with the smaller mass
E) the one with the higher specific heat

8. ConcepTest 17.7 Ideal Gas Law I
Two identical cylinders at the same temperature contain the same gas. If A contains three times as much gas as B, which cylinder has the higher pressure?
A) cylinder A
B) cylinder B
C) both the same
D) it depends on temp. T

9. ConcepTest 17.8 Ideal Gas Law II
Two identical cylinders at the same pressure contain the same gas. If A contains three times as much gas as B, which cylinder has the higher temperature?
A) cylinder A
B) cylinder B
C) both the same
D) it depends on the pressure P

10. ConcepTest 17.9 Ideal Gas Law III
Two identical cylinders at the same temperature contain the same gas. If B has twice the volume and half the number of moles as A, how does the pressure in B compare with the pressure in A?
A) PB = 1/2 PA
B) PB = 2 PA
C) PB = 1/4 PA
D) PB = 4 PA
E) PB = PA

11. ConcepTest 17.10 Soda Bottle
A plastic soda bottle is empty and sits out in the sun, heating the air inside. Now you put the cap on tightly and put the bottle in the fridge. What happens to the bottle as it cools?
A) it expands and may burst
B) it does not change
C) it contracts and the sides collapse inward
D) it is too dark in the fridge to tell

12. ConcepTest 17.11 Balloon in Freezer
A) it increases
B) it does not change
C) it decreases
What happens to the volume of a balloon if you put it in the freezer?
