CBSE Class 11-science Chemistry States of Matter
Dipole-dipole forces exist between polar molecules, dipole-induced dipole forces exist between polar and non-polar molecules and London Forces also called dispersion forces exist between non polar molecules.
Hydrogen bonding is special type of Dipole-dipole force.
Effect of Heat on Matter
Higher melting and boiling point of substances are due to size i.e. higher molecular weight and intermolecular forces.
Properties like sublimation and compressibility are affected by intermolecular forces.
Amount of gas-volume relation is known as Avogadro's law.
Dalton's law of partial pressure states that the total pressure of a mixture of non-reactive gases is the sum of individual pressures exerted by each gas.
Ideal Gas Equation.
Under suitable conditions of temperature and pressure conditions gases can be liquefied.
The critical temperature is the temperature above which distinct liquid and gas phases do not exist.
Properties of Liquid
Surface tension is defined as the force acting at right angles per unit length.
Viscosity is the measure of resistance to flow. Increase in temperature decreases surface tension and viscosity.
