The lattice energy is the energy released when one mole of the ionic crystal is formed from the gaseous ions. OR It is also defined as the energy required to break one mole of the solid into isolated ions in the gas phase. Explanation with […]
Greater the pressure exerted on the liquid, greater would be the boiling point or vice versa. Boiling point of a liquid can be increased by increasing the external pressure on the liquid, whereas it can be decreased by decreasing the external pressure on the liquid. […]
In order to bring about phase change, latent heat is absorbed without any change in temperature. Because heat energy stored in steam is greater than that of boiling water at same temperature. Therefore steam produces more severe burns than does the boiling water.
When a liquid is heated, the kinetic energy of its molecules increases in other words the temperature increases as well as the rate of vaporization increases. When the kinetic energy of the molecules becomes maximum i.e., boiling point is reached any further heating at this […]
The pressure above the surface of the liquid by the vapours at equilibrium between liquid and its vapours at a particular temperature is called equilibrium vapour pressure or simply vapour pressure. Explanation: If we enclosed a liquid in a vessel, molecules start to evaporate above […]
Definition: The spontaneous escaping of molecules of a liquid from their surface at any temperature is called evaporation. Evaporation Process: Most common question in this regard is, How does evaporation work? All the liquid molecules do not contain the same kinetic energies. Speed of molecules […]
