Answers
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:
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
