.Differentiate between-
a.Boiling point and melting point
b.Diffusion in solid and diffusion in liquid
c.Boiling and evaporation
Answers
Answer:
boiling point is a point when any liquid start boiling is called boiling point
melting point is a point where a solid substance start melting is known as melting point
boiling is a process in which a liquid start boiling
evaporation is a process in which after boiling the liqud start boiling is called evaporation
Explanation:
Melting point:Melting point is the temperature at which a solid becomes a liquid at normal atmospheric pressure.
Boiling point: Temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and liquid change to vapor (and vice versa).
Evaporation:Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure.
Diffusion in solids: Diffusion does not happen in solids because the particles are not free to move around and so they cannot inter-mix.
Diffusion in liquids: When substances dissolve in liquids (like salt dissolving in water) the substances spread out. We call this spreading out of dissolved particles diffusion. The end result of this is that the solute particles that have dissolved in water will spread out evenly. This movement or spreading out is due to the fact that in liquids the particles are moving randomly.
