pls ans above question​

Answer 1

Answer:

According to Boyle's Law, the pressure of a gas is inversely proportional to the volume occupied by it at a fixed or a constant temperature.

In terms of a mathematical equation, it is given as:

$\implies P \:\: \alpha \;\: \dfrac{1}{V}\\\\\\\implies PV = \text{constant}$

According to the question, it is given that:

• Volume of Ethene before changing pressure = 2.5 dm³
• Volume of Ethene after changing pressure = 1.25 dm³
• Initial Pressure = 1.05 atm
• Final Pressure = 2.10 atm
• Temperature = Constant

Now we can see that when the pressure was 1.05 atm, the volume was 2.5 dm³. But once the pressure was increased 2 times to 2.10 atm, the volume decreased to half of its original value 1.25 dm³

⇒ P₁V₁ = P₂V₂ = constant

Hence the change is corresponding to Boyle's Law.
