Question

Does Boyle’s Law state that as volume increases, pressure decreases or as pressure increases, volume decreases?

Answer 1

Hint:Boyle's Law is basically an experimental gas law that explains how the pressure of a gas varies with its volume. It also tells us how the pressure of gas increases as the volume of a particular container decreases. Boyle’s law is also well known as the Boyle–Mariotte law.

Complete step by step answer:
Boyle's Law states that the pressure and volume are both inversely proportional to each other, but it also assumes that the material should be a confined gas and the temperature should also remain steady.
Mathematically, it can be stated as,
$P \propto \dfrac{1}{V}$
This relation can also be written as,
$PV = k$
Where $k$ is a constant.
The equation also tells us that if the temperature holds constant, then the product of pressure and volume is a constant for a particular mass of confined gas.

Additional information: An example of Boyle's law is the action which takes place in a balloon. When air is blown in a balloon, then the pressure of that air pushes the rubber and this makes the balloon expand. If one of the ends of a balloon is squeezed, making the volume smaller, then the pressure inside it is increased and this further makes the un-squeezed part of the balloon expand out.

Note:In order to understand other such laws, we need a clear understanding of the concept of ideal gas. An ideal gas is a theoretical gas which is made up of lots of arbitrarily moving point particles whose interactions are completely elastic in nature. The theory of ideal gas is very useful as it obeys the ideal gas law, which is a simplified equation of state.
