Question

Define:

i.Melting point

ii.Boiling point

iii.Vapourisation

iv.Freezing

v.Brownian motion​

Answer 1

Answer:1. the temperature at which a given solid will melt.

2. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.

3. Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapour.

4. Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point.

5. the erratic random movement of microscopic particles in a fluid, as a result of continuous bombardment from molecules of the surrounding medium.

Answer 2

Answer:

melting point

a stage is reached when solid melts and is converted to liquid

a minimum temperqture at which a solid melts to become liquid is called melting point

boiling point

it is the temperature when the vapour pressure of liquid equals the pressure surrounding the liquid and then liquid changes go vapour

vapourisation

it is the phase transition from the liquid to vapour

freezing

it is a phase transition where a liquid changes to solid
