Question

when a liquid starts boiling its temperature does not rise till the complete liquid has boiled. explain​

Answer 1

Answer:

because there is presence of latent heat

Explanation:

when we use to continuously heat but the temp. doesn't rise because

Answer 2

$\huge\text{\underline{Answer}}$

when a liquid starts boiling its temperature does not rise till the complete liquid has boiled.

This is because the heat supplied is used to change the states of liquid from liquid states to gaseous state.

This is also known as latent heat .

Because all the heat energy supplied is lost in breaking the attraction forces between the molecules of water due to this the temperature of liquid is not rise.

Till the all liquids get converted in to vapours.

This heat energy is stored by steams known as $\bold{Latent heat of vapourisation.}$
