Why was the line of best fit method used to determine the experimental value of absolute zero?

Answer:
<u><em></em></u>
- <u><em>Because the x-intercet of the graph represents volume zero, which indicates the minimum possible temperature or absolute zero.</em></u>
Explanation:
Charle's Law for ideal gases states that, at constant pressure, the <em>temperature</em> and the <em>volume</em> of a sample of gas are protortional.
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 (<em>absolute zero</em>) as the minimum possible volume is zero.

Explanation: An element is represented in the form of where,
X = Symbol of the element
A = Atomic Mass of the element X
Z = Atomic Number of element X
Hence, For the element Justwondoricium,
Symbol = Jw
Atomic number = 120
Atomic Mass = 224
Now, Atomic number = Number of electrons = Number of Protons
Number of electrons = 120
Number of Protons = 120
and Atomic Mass = Number of neutrons + Number of protons
Number of neutrons can be calculated as we know atomic mass and number of neutrons, Putting the numbers we get
Number of neutrons = 224 - 120 = 104
The nearest noble gas to the element having atomic number 120 is Oganesson (Og), which has an atomic number of 118, so the next two electrons will be filled in the 8s orbital.
Electronic Configuration of Jw is
This electronic configuration lets us know about the location of the element in periodic table.
As the electron is entering the 8th shell, it belongs to the 8th period and as the last electron enters the s-orbital, it belongs to the S-block of the periodic table.
When the s-electrons are 1, it belongs to Group 1.
When the s-electrons are 2, it belongs to Group 2.
As this element has 2 s-electrons, it belongs to the Group 2.
