States of Matter
(Also known as van der Waals forces)
Dispersion forces or London forces (Forces between atoms or non-polar molecules)
Dipole-dipole forces (Forces between molecules possessing permanent dipole)
Dipole-induced forces (Forces between a molecule having permanent dipole and a molecule lacking permanent dipole)
- Ion-dipole interaction (Interaction of an ion with the oppositely charged site of a polar moleule)
Hydrogen bond (Force between hydrogen attached to an electronegative atom of one molecule and an electronegative atom of different molecule)
Thermal energy: Energy of a body due to motion of its atoms or molecules
Relation between pressure (p) and volume (V)
Statement − At constant temperature, the pressure of a fixed amount (number of moles, n) of a gas is inversely proportional to its volume.
Relation between temperature (T) and volume (V)
Statement − At constant pressure, the volume of a fixed amount of a gas is directly proportional to its absolute temperature.
Standard Temperature and Pressure(STP)
The standard values are 00C or 273K for temperature and 1 atm or 760 mm of Hg for pressure and ar…
