Answer:
- Because the x-intercet of the graph represents volume zero, which indicates the minimum possible temperature or absolute zero.
Explanation:
Charle's Law for ideal gases states that, at constant pressure, the temperature and the volume of a sample of gas are protortional.
[tex]\dfrac{V}{T}=k\\\\V=kT[/tex]
That means that the graph of the relationship between Temperature, in Kelivn, and Volume is a line, which passes through the origin.
When you work with Temperature in Celsius, and the temperature is placed on the x-axis, the line is shifted to the left 273.15ºC.
Meaning that the Volume at 273.15ºC is zero.
You cannot reach such low temperatures in an experiment, and also, volume zero is not real.
Nevertheless, you can draw the line of best fit and extend it until the x-axis (corresponding to a theoretical volume equal to zero), and read the corresponding temperature.
Subject to the experimental errors, and the fact that the real gases are not ideal, the temperature that you read on the x-axis is the minimum possible temperature (absolute zero) as the minimum possible volume is zero.
Because the [tex]x-[/tex]intercept of the graph it shows volume zero, which signifies the lowest feasible temperature or absolutely zero, the arc of best fit approach can be used to estimate the theoretical values of absolute zero.
Define Line of best fit.
The best fit line is a line that runs through a scatter diagram of data points and best reflects the relationship between them.
Manual computations or regression analyzer could be used to get at the geometric solution for the line using the least squares approach.
