Universal Gas Constant (Noun)
Meaning
(physics) the universal constant in the gas equation: pressure times volume = R times temperature; equal to 8.3143 joules per kelvin per mole.
Classification
Nouns denoting quantities and units of measure.
Examples
- The ideal gas law, PV = nRT, is a fundamental concept in physics and chemistry, where R is the universal gas constant.
- The ideal gas law is a simplified equation of state for gases, and R, the universal gas constant, is a key component that relates pressure, volume, and temperature.
- In order to calculate the number of moles of a gas, we need to use the universal gas constant, R, in the ideal gas equation PV = nRT.
- The value of the universal gas constant, R, has been measured and calculated with great precision, and is currently accepted to be 8.3143 joules per kelvin per mole.
- In thermodynamics, the universal gas constant, R, is a crucial element in many equations, including the ideal gas law, PV = nRT.
