Question

Volume is inversely proportional to pressure is:
A: Boyle’s law
B: Charle’s law
C: Avogadro's law
D: Ideal gas law
E: Dalton's law

Answer 1

Hint: Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases.

Complete step by step answer:
Before doing the question firstly we have to understand about each law given. First of all let's understand about Charles Law : Charles's law states that at Constant pressure, the volume of a given mass of a gas is directly proportional to its temperature in degree Kelvin i.e.
$V \propto T$ Or $\dfrac{V}{T}$ =Constant $V \propto n$be the partial pressure of n gases enclosed in a given vessel and P be the total pressure of the gaseous mixture, then the Dalton's Law be expressed as
P= ${P_1},{P_2},{P_3}.........{P_n}$.
In the end, we have remained with only Boyle 's law which states that at Constant temperature , the volume of gas is inversely proportional to the pressure of gas or product of pressure and volume of given mass of a gas is constant, i.e.
$V \propto \dfrac{1}{P}$ or PV= constant.
Hence option A is correct.

Note:As we have said that gas which satisfies the ideal gas equation under every condition is called ideal gas. But the truth is that no gas is purely ideal - All gases deviate from the ideal gas equation at certain conditions and thus are called real gases. But real gases behave as ideal only when pressure is low and Temperature is high.
