Bowling ball

Conversions of the type we have just carried out come up over and over again in chemistry. They will be required in nearly every chapter of this text Clearly, you must know what is meant by a mole. Remember, a mole always represents a certain number of items, 6.022 X 1023. Its mass, however, differs with the substance involved A mole of H20,18.02 g, weighs considerably more than a mole of H 2.016 g, even though they both contain the same number of molecules. In the same way, a dozen bowling balls weigh a lot more than a dozen eggs, even though the number of items is the same for both. 

Figure 11-4 Two bowling balls falling in still water at 25 ft/s. The ball on the left is smooth, and the one on the right has a patch of sand on the nose. (From Coulson et at, 1991.)...

A monomer called methylmethacrylate polymerizes to form an addition polymer that is used to make bowling balls. What is the name of this polymer ... 

This robot will drill all the holes in our bowling balls from now on I also want to announce that I am giving Arney Beagle a new job. He will be in charge of the Winsock 2000 Bowling Ball Drilling Robot."... 

Table 10.3 summarizes the uses of propylene oxide. Propylene glycol is made by hydrolysis of propylene oxide. The student should develop the mechanism for this reaction, which is similar to the ethylene oxide to ethylene glycol conversion (Chapter 9, Section 8). Propylene glycol is a monomer in the manufacture of unsaturated polyester resins, which are used for boat and automobile bodies, bowling balls, and playground equipment.

A bowling ball with mass 8.00 kg is rolled down a bowling alley lane at 5.00 0.05 m-s 1. What is the minimum uncertainty in its position ... 

The mass of the electron The lighter the particle, the greater its deflection. (Just as it s easier to deflect a Ping-Pong ball than a bowling ball.)... 

The number of molecules or bowling balls at height h, which we will call n/, can be compared to the number no at h = 0 by Equation 4.28 ... 

This predicts that bowling balls do not float any significant distance above the floor— in accord with our expectation. However, the situation for oxygen molecules is quite different. At a height of approximately 8000 m, mgh/ kT k,, and the concentration of oxygen molecules has fallen to about 1/e of its value at sea level (if we assume no temperature variations). 

A noise comes from a faraway hallway. It sounds like bowling balls rolling down a long alley. Please move close to the walls, says Ishmael. The Nephilim nod. 

This illustration shows an atom as John Dalton (1766-1844) imagined it. Many reference materials refer to Dalton s concept of the atom as the "billiard ball model. Dalton, however, was an avid lawn bowler. His concept of the atom was almost certainly influenced by the smooth, solid bowling balls used in the game. 

De Broglie developed an equation that allowed him to calculate the wavelength of the matter wave associated with any object, from a bowling ball to an electron. Objects that we can see and can interact with have calculated wavelengths that are smaller than electrons. Their wavelengths are so tiny compared to their size that they do not have any measurable effect on the motion of the objects.
