In the equation PV = nRT, the value of 'R' will not depend on
A.Nature of gas
B.Pressure
C.Temperature
D.Units of measurements
Solution
Hint: The ideal gas law combines the relationships between p, V, T and mass, and gives a number to the constant. The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant.
Complete answer:
In the equation, PV = nRT, R is the universal gas constant. The value of R will not depend on the nature of gas, pressure, and temperature. It will depend on the units of measurements.
For example, the values of R include 8.314 J/mol/K, 2 cal/mol/K and 0.08206 Latm/mol/K.
Note: The gas constant (also known as the molar, universal, or ideal gas constant) is denoted by the symbol R. It is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure–volume product, rather than energy per temperature increment per particle.
