Gas Laws Calculator

A Gas Laws Calculator is an online tool that helps you calculate how gases behave as the temperature, pressure, volume, and number of moles change. This calculator uses basic gas laws to rapidly and accurately find unknown values. We can use the Ideal Gas Laws—Boyle’s law, Charles’s law, Gay-Lussac’s law, and the Combined Gas Law—to understand how different physical properties of gases are related.

How to Use a Gas Laws Calculator?

  • Step 1: Choose the law that you want to calculate.
  • Step 2: Entered all required inputs
  • Step 3: Click on “calculate: and you see the results in seconds.

Example 1: Choose Law Type “Boyle's Law (P₁V₁ = P₂V₂)”

What is the final volume (V₂) of a gas given an initial pressure of 8 atm, a final pressure of 2 atm, and an initial volume of 4 L?
Inputs:

  • Find Final Volume (V₂)?
  • Initial pressure (atm)=8
  • Initial Volume (L)=4
  • Final pressure (atm)=2
  • Final Volume (L)=?

Step by step:

  • Boyle's Law: P₁V₁ = P₂V₂ (constant temperature)
  • V₂ = P₁V₁/P₂ = (8×4) / 2

result:

  • Final volume = 16 L

Example 2: Choose Law Type “Charles’ Law (V₁/T₁ = V₂/T₂)”

When a gas’s initial volume is 2 L, its initial temperature is 300 K, and its final temperature is 600 K, what is its final volume (V₂)?
Inputs:

  • Find Final Volume (V₂) =?
  • Initial Volume (L): 2
  • Initial Temperature (K): 300
  • Final Temperature (K): 600

Step by step:

  • Charles' Law: V₁/T₁ = V₂/T₂ (constant pressure)
  • V₂ = V₁T₂/T₁ = (2×600) / 300

result:

  • Final volume = 4 L

Example 3: Choose Law Type “Gay-Lussac’s Law (P₁/T₁ = P₂/T₂)”

If a gas’s initial pressure is 1 atm, its initial temperature is 273 K, and its final temperature is 546 K, what is its final pressure (P₂)?
Inputs:

  • Final Temperature (K): 546
  • Initial Temperature (K): 273
  • Initial pressure: 1
  • Final pressure:?

Step by step:

  • Gay-Lussac's Law: P₁/T₁ = P₂/T₂ (constant volume)
  • P₂ = P₁T₂/T₁ = (1×546) / 273

result:

  • Final pressure = 2 atm

Example 4: Choose Law Type “Combined Gas Law (P₁V₁/T₁ = P₂V₂/T₂)”

What is the final pressure (P₂) of a gas with an initial pressure of 3 atm, an initial volume of 2 L, a final volume of 4 L, an initial temperature of 300 K, and a final temperature of 400 K?
Inputs:

  • Initial pressure (atm): 3
  • Initial Volume (L): 2
  • Initial Temperature (K): 300
  • Final Volume (L): 4
  • Final Temperature (K): 400
  • Final pressure (atm)?

Step by step:

  • Combined Gas Law: P₁V₁/T₁ = P₂V₂/T₂
  • P₂ = (P₁V₁T₂)/(T₁V₂)

result:

  • Final pressure = 2 atm
