Question

Name the process take place when wax is melt? Vapourisation Liquefaction Condensation Sublimation​

Answer 1

Answer:

vapourisation

When you light a candle, the heat of the flame melts the wax near the wick. This liquid wax is then drawn up the wick by capillary action. The heat of the flame vaporizes the liquid wax (turns it into a hot gas), and starts to break down the hydrocarbons into molecules of hydrogen and carbon.

hope it helps :-)

Solution :

(a) Melting - The conversion of a solid to its liquid state is melting.

(b) Vaporisation - The conversion of a liquid to its gaseous state i.e. vapours by heating is vaporisation.

(c) Condensation - The conversion of vapor in gaseous state to its liquid state by cooling is condensation.

(d) Freezing - The conversion of a liquid to its solid state is freezing.

(e) Melting point - The temperature at which solid melts into liquid is melting point.

(f) Boiling point - The temperature at which water boils and turns into vapou
