The given equation is [tex]P_{1} V_{1}=P_{2} V_{2}[/tex], illustrated and derived through the Boyle’s law.
Explanation:
Boyle’s law derived the conditions of the sample of a gas in two different conditional pressure and volume. The initial observation was that the product of a given pressure and volume for the sample of gas at a constant temperature is observed to be constant.
Therefore,
[tex]P \times V=\text { constant}[/tex]
The two temperature conditions were thus observed and the equation was elaborated to be,
[tex]P_{1} V_{1}=P_{2} V_{2}[/tex]
