ICSE Class 9 Chemistry The behaviour of gases under changes of temperature and pressure
Avogadro law states that the total number of atoms/molecules of a gas is directly proportional to the volume occupied by the gas at constant temperature and pressure.
Value of molar gas constant is 8.314 J / mol·K.
Use Charles law.
High pressure and low temperature
Boyle's law states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.
Ideal gas equation
PV = nRT
High temperature and low pressure.
One atm. equals 760.0 mm Hg.
