This Boyle’s law calculator calculates different physical parameters like temperature, pressure, and volume of a gas enclosed in a gas container.

What Is Boyle’s Law?

“At a constant temperature, the volume of a gas is inversely proportional to the pressure applied to it”

Boyles Law Formula:

The Boyle’s law equation is as follows:

\(P_{1}*V_{1} = P_{2}*V_{2}\)


\(P_{1}\) = Initial temperature of the gas

\(V_{1}\) = Initial volume of the gas

\(P_{2}\) = Final gas pressure

\(V_{2}\) = Final volume of the

You can use this pressure volume calculator that describes the most accurate estimations of pressure and volume of any gas that may be packed in a closed object.

Boyle’s Law Example Problems:

In this section of the read, we will resolve an example so as to clarify your concept regarding pressure and volume calculations. Let’s move on!

Example # 01:

How to find final pressure of a gas enclosed in a certain container with following parameters given:

\(P_{1}\) = 34Pa

\(V_{1}\) = 2\(m^{3}\)

\(V_{2}\) = 5\(m^{3}\)


Here we have the pressure volume equation as follows:

\(P_{2} =\dfrac{P_{1}*V_{1}}{V_{2}}\)

\(P_{2} =\dfrac{34*2}{5}\)

\(P_{2} =\dfrac{68}{5}\)

\(P_{2} = 13.6Pa\)

Why Does Volume Decrease When Pressure Increases?

When a certain amount of pressure is applied to the gas, its particles get close to one another. This decreases the overall volume of it while enhancing the pressure applied. You can also check it by using this Boyle’s law calculator in seconds.

Does Heat Increase Volume?

Yes, of course! According to Charle’s law, increasing the temperature of the gas will enhance its molecules’ speed. This is because they are spread apart speedily and increase the final volume. You can understand this kind of relationship by using Charle’s law calculator.
