Question
Chapter 4, Problem 1LC
To determine
To differentiate: Temperature and heat.
Expert Solution & Answer
Answer to Problem 1LC
While temperature defines the “average kinetic energy of the molecules in a substance”, heat is the form of energy that gets transferred from one substance to another due to the difference existing in their temperatures. The heat flows from a hot object to the cold one by raising its internal energy.
Explanation of Solution
The “average kinetic energy” possessed by the molecules of a substance defines its temperature. It may be more precisely the kinetic energy due to the translational motion of the molecules composing a substance. The more vigorous the movement is, the more will be the kinetic energy and the higher will be the temperature of the substance.
The difference in temperature will lead to transmission of energy. This energy transmitted from one object to another is known as heat. Usually, the direction of heat energy transfer will be from a body at higher temperature to the ones at lower temperature. The hotter substance from where the transfer occurs, undergoes a decline in its internal energy, while the cold substance to which the heat energy got transferred experiences a rise in its internal energy.

As a result, some of this region has recently been uplifted and exhibits characteristics of an emergent coastline.

Refer to this topographic map to complete the following. 1. What type of shoreline feature is Drakes Estero (located near the center of the map)? 2. Point Reyes, located in the bottom-left corner of the map, is a headland undergoing severe wave erosion. What type of feature is Chimney Rock, located off the shore of Point Reyes? 3.

At approximately what water depth-10, 20, 30, or 40 feet-will the approaching waves begin to touch bottom and slow down? (Hint: Recall that this occurs when the water depth is one-half the wavelength.) 2. Using the wave shown in Figure 12.2 as a starting point, sketch a series of lines to illustrate the wave refraction that will occur as the wave approaches the shore by following these steps:Step 1: Mark the position on the 30-foot contour line where the wave front will first touch bottom.Step 2: Knowing that the section of the wave that touches bottom will slow down first, sketch the shape of the wave front when it reaches the 20-foot contour line.Step 3: Using the same…arrow_forward
