Question

water vapour at 373 Kelvin have more energy than water at the same temperature why

Answer 1

it takes up more latent heat

Answer 2

__________________________


$\sf{\underline{\underline{The\:boiling\:point\:of\: water\:is\:373\:K.}}}$


At this temperature,

$\sf{\underline{Water\:vapours\:and\:liquid\:water\: coexist.}}$



In order to convert liquid water into vapours,

$\sf{\underline{\underline{Additional\:energy\:is\: required.}}}$


This additional energy which converts water at 373 K to steam is known as 'latent energy of vaporisation.'


$\sf{\underline{\underline{Hence,}}}$

The water vapours have a lot more heat energy than liquid water at the same temperature.


$\sf{\underline{Therefore,\:it\:is\:more\:effective\: in\:heating.}}$
