Question

what is the definition of universal gas constant​

Answer 1

Answer:

hope it's help u ☺☺✌

Explanation:

The gas constant, also known as the universal molar gas constant, is a physical constant that appears in an equation defining the behavior of a gas under theoretically ideal conditions. The gas constant is, by convention, symbolized R.

The pressure, volume, amount of substance, and temperature of a gas are related according to the following equation, known as the universal gas equation:

PV = NRT

where P represents the pressure in pascals, V represents the volume in meters cubed, N represents the amount of substance in moles, and T represents the absolute temperature in kelvins.

In terms of the pressure, volume, amount of substance, and temperature, the gas constant is equal to:

R = (PV) / (NT)

The gas constant has been found, by experiment, to have a value of approximately 8.3145 joules per kelvin per mole (J · K-1 · mol-1).

Answer 2

Answer:

Explanation: universal gas constant is the amount of work done on one mole of gas to increase the temperature by 1Kelvin.

PV =nR T

R is universal gas constant

Value of R

Is =8.314J/k/mol

=0.083Latm/k/mol

=0.082Lbarr/k/mol

=1.98cal /k/mol
