Question

ideal gas equation when pressure in torr and volume in Liter

Answer 1

 three historically important gas laws derived relationships between two physical properties of a gas, while keeping other properties constant:



These different relationships can be combined into a single relationship to make a more general gas law:



If the proportionality constant is called "R", then we have:



Rearranging to a more familiar form:



This equation is known as the ideal-gas equation

An "ideal gas" is one whose physical behavior is accurately described by the ideal-gas equation

The constant R is called the gas constant

The value and units of R depend on the units used in determining P, V, n and T

Temperature, T, must always be expressed on an absolute-temperature scale (K)

The quantity of gas, n, is normally expressed in moles

The units chosen for pressure and volume are typically atmospheres(atm) and liters (l), however, other units may be chosen

PV can have the units of energy:
