Calculate Absolute Zero of a Gas from Data Chegg
Absolute zero is the lowest possible temperature, defined as 0 Kelvin or -273.15 degrees Celsius. Calculating the absolute zero of a gas is crucial in various scientific and industrial applications. Our calculator helps you determine the absolute zero of a gas given its pressure.
How to Use This Calculator
- Select the gas from the dropdown menu.
- Enter the pressure of the gas in Pascals (Pa).
- Click the ‘Calculate’ button.
Formula & Methodology
The formula to calculate the absolute zero of a gas is:
T = 273.15 – (11.4 * log(P))
where T is the absolute zero temperature in Kelvin, P is the pressure of the gas in Pascals, and log is the common logarithm (base 10).

Interactive FAQ
What is the absolute zero temperature of helium at 1 atm?
The absolute zero temperature of helium at 1 atm is 0.95 K.
How does pressure affect the absolute zero temperature?
As pressure increases, the absolute zero temperature decreases. This is because the intermolecular forces increase with pressure, making it harder for the molecules to move and thus lowering the temperature.
