## What is the value of R in lit ATM unit?

If you use the first value of R, which is 0.082057 L atm mol-1K-1, your unit for pressure must be atm, for volume must be liter, for temperature must be Kelvin.

## What is the value of R in joule?

The dimensions of the universal gas constant R are energy per degree per mole. In the metre-kilogram-second system, the value of R is 8.3144598 joules per kelvin (K) per mole.

## What is the value of R in Pascal?

When pressure is measured in Pascals, R=8.314⋅m3⋅Pa⋅K−1mol−1 .

## What are the different values of r?

The value of the gas constant ‘R’ depends on the units used for pressure, volume and temperature.

• R = 0.0821 liter·atm/mol·K.
• R = 8.3145 J/mol·K.
• R = 8.2057 m3·atm/mol·K.
• R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K.

## What units are used in 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). R has the value 8.314 J/(K.

## What does Boyles law mean?

This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form, pv = k, a constant. …
