Question

The ideal gas equation is

• A. PV = constant
• B. PT = constant
• C. V/T = nPR
• D. PV = nRT

Answer 1

The correct option is D PV = nRT

The ideal gas law is $\text{PV}=\text{nRT}$, where

• $\text{P}$ is the pressure of the gas
• $\text{V}$ is the volume of the gas
• $\text{n}$ is the amount of substance of gas in moles
• $\text{R}$ is the ideal, or universal gas constant, equal to the product of the Boltzmann constant ($\text{k}$) and the Avogadro's number (${\text{N}}_{\text{A}}$)
• $\text{T}$ is the absolute temperature of the gas in kelvin
