What are intermolecular forces?
These are the weak attractive forces existing in gases, liquids, and solids. For examples,
(i) Dispersion forces or London forces.
(ii) Dipole- dipole interactions .
(iii) Dipole-induced dipole interactions.
(iv) Hydrogen bond -stronger intermolecular interaction.
A manometer is connected to a gas containing bulb. The open arm reads 43.7 cm where the arm connected to the bulb reads 15.6 cm. If the barometric pressure is 743 nm mercury what is the pressure of the gas in a bar?
