Question
Chapter 18, Problem 3A
To determine
The evidence for the microscopic crystal nature of some solids.
Expert Solution & Answer
Explanation of Solution
Introduction:
The particles of crystal are arranged in an ordered repeated pattern. Crystals are regularly geometric shapes.
When metals etch with acids, crystals in the metals are seen. The surface of galvanized ironexposed to weather and brass doorknobs etched by an impression of hands are the evidence of the crystal nature of some solids.
Conclusion:
Iron exposed to the weather and brass doorknobs is the evidence of the crystal nature of some solids.

To do this, you first explain about Einstein's notion of large masses, like those of stars, causing a curvature of spacetime. (See the section on general relativity.) To demonstrate, you put a bowling ball on your bed, so that it sinks downward and creates a deep depression in the mattress. Your sheet has a checked pattern that provides a nice coordinate system, as shown in the figure below. This is an example of a large mass (the bowling ball) creating a curvature of a flat, two-dimensional surface (the mattress) into a third dimension. (Spacetime is four dimensional, so its curvature is not easily visualized.)
