Chapter 1: Problem 43

Below is a plot of the temperature of the calorimeter versus time: cant copy graph Which point on the graph represents \(T f ?\) 1\. A 2\. \(\mathrm{B}\) 3\. \(\mathrm{C}\) 4\. D

Short Answer

Expert verified
The final temperature, $T_f$, is represented by the point on the graph where the temperature becomes stable or changes only minimally after a significant period of time has passed, indicating thermal equilibrium. To determine which point corresponds to $T_f$, analyze the graph and match the point of temperature stability with one of the given options (1. A, 2. B, 3. C, or 4. D).

Step by step solution

01

Identify the temperature on the y-axis

First, take a look at the y-axis of the graph. The y-axis represents the temperature of the calorimeter. Each point on the graph has a temperature value associated with it.
02

Analyze the time on the x-axis

Now, take a look at the x-axis of the graph. The x-axis represents the time. The final temperature, Tf, will typically be found at a point where the temperature change is no longer significant, meaning the temperature has become relatively stable.
03

Find the point of temperature stability

Look for the point on the graph where the temperature becomes stable or changes only minimally after a significant period of time has passed. Keep in mind that a stable or nearly constant temperature over time represents reaching a thermal equilibrium, which is the final temperature, Tf.
04

Match the point to the given options

Now that you identified the point representing the final temperature, match the point on the graph with the given options (1. A, 2. B, 3. C, or 4. D). This will determine which point represents Tf.

Why does an incandescent light have a longer life when an inert gas is used rather than a vacuum? 1\. The filament vaporizes more slowly. 2\. Heat is removed from the filament. 3\. The bulb is less likely to implode when subjected to vibration. 4\. The gas directly absorbs energy from the electrons in the filament.
