Chapter 18: Q. 1 (page 490)
Rank in order, from highest to lowest, the temperatures
T1 = 0 K, T2 = 0 C, and T3 = 0 F.
The solution gives the description of temperature from lowest to highest. jsnviunsdiuvniusnvijnkjsn vsubvuybsuvb

The U-shaped tube in FIGURE P18.57 has a total length of . It is open at one end, closed at the other, and is initially filled with air at pressure.
Mercury is poured slowly into the open end without letting any air escape, thus compressing the air. This is continued until the open side of the tube is completely filled with mercury. What is the length of the column of mercury?
3.0 mol of gas at a temperature of -120C fills a 2.0 L
container. What is the gas pressure?
A student is asked to sketch a pV diagram for a gas that goes
through a cycle consisting of (a) an isobaric expansion, (b) a
constant-volume reduction in temperature, and (c) an isothermal
process that returns the gas to its initial state. The student draws
the diagram shown in FIGURE Q18.12. What, if anything, is wrong
with the student’s diagram?
On average, each person in the industrialized world is responsible for the emission of of carbon dioxide (data-custom-editor="chemistry" ) every year. This includes that you generate directly, by burning fossil fuels to operate your car or your furnace, as well as generated on your behalf by electric generating stations and manufacturing plants. is a greenhouse gas that contributes to global warming. If you were to store your yearly emissions in a cube at STP, how long would each edge of the cube be?
A diving bell is a -tall cylinder closed at the upper end but open at the lower end. The temperature of the air in the bell is . The bell is lowered into the ocean until its lower end is deep. The temperature at that depth is .
a. How high does the water rise in the bell after enough time has passed for the air inside to reach thermal equilibrium?
b. A compressed-air hose from the surface is used to expel all the water from the bell. What minimum air pressure is needed to do this?
