asked in category: General Last Updated: 6th March, 2020# Is PV nRT in Kelvin?

**Kelvin**) The correct units are essential. Be sure to convert whatever units you start with into the appropriate units when using the ideal gas law.

Also to know is, what is the value of R in PV nRT?

The ideal gas law is: **pV** = **nRT**, where n is the number of moles, and **R** is universal gas constant. The **value of R** depends on the units involved, but is usually stated with S.I. units as: **R** = 8.314 J/mol·K.

Beside above, how do you calculate PV nRT? **The properties of an ideal gas are all lined in one formula of the form pV = nRT , where:**

- p is the pressure of the gas, measured in Pa,
- V is the volume of the gas, measured in m^3,
- n is the amount of substance, measured in moles,
- R is the ideal gas constant and.
- T is the temperature of the gas, measured in Kelvins.

Likewise, do you have to use Kelvin for ideal gas law?

For all **gas law** problems it is necessary to work in the **Kelvin** scale because temperature is in the denominator in the **combined gas laws** (P/T, V/T and PV/T) and **can** be derived in the **ideal gas law** to the denominator (PV/RT) .

What are the units for PV nRT?

In SI units, p is measured in **pascals**, V is measured in cubic metres, n is measured in moles, and T in **kelvins** (**the Kelvin scale** is a shifted **Celsius scale**, where 0.00 K = −273.15 °C, the lowest possible temperature).
