ICSE Class 9 Chemistry The behaviour of gases under changes of temperature and pressure
|
The molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample.
Experimental gas law that describes how gases tend to expand when heated.
One atm. equals 760.0 mm Hg.
it is given by the equipartition theorem as, E=3kT2
Use Charles law.
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.
Charles law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.
Straight line
Boyle's law states that the pressure (p) of a given quantity of gas varies inversely with its volume.
High pressure and low temperature
