Question
Chapter 19, Problem 1ASA
To determine
The cause of the thermal expansion on the molecular level.
Expert Solution & Answer
Answer to Problem 1ASA
As the substance temperatures increase, the internal energy increases, forcing the atoms or molecules to vibrate back and forth that causes the change in shape of the material.
Explanation of Solution
There is certain internal energy in every material. The atoms or molecules are connected as a single entity in the substance by a strong attractive force. The atoms are held more specifically as two masses associated with spring at either end.
Conclusion:
Thermal expansion is the behavior of matter in response to changes in its shape, area and volume.
As the substance temperatures increase, the internal energy increases, forcing the atoms or molecules to vibrate back and forth. The net vibration of the atoms should be so large that the material might lose its shape.

Two moving charged particles exert forces on each other because each creates a magnetic field that acts
on the other. These two "Lorentz" forces are proportional to vix (2 xr) and 2 x (vi x-r), where is the vector
between the particle positions. Show that these two forces are equal and opposite in accordance with Newton's third
law if and only if rx (vi × 2) = 0.

What would its speed be when it is very far from the Earth (in m/s)? Ignore atmospheric friction, the effects of other planets, and the rotation of the Earth. (Consider the mass of the Sun in your calculations.) Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation.

During the one-armed maneuver first developed in the 1940s, the outstretched arm of the male skater must apply a large force to support a significant fraction of the female skater's weight and also to provide her centripetal acceleration. This force represents a danger to the structure of the wrist of the male skater.

This slide was unique for its time due to the fact that a large number of small wheels along its length made friction negligible.
