Question

Particle in steam at 100 c° ( 373 k ) have more energy than water at same room temperature why ?

Answer 1

The room temperature is about 20°C to 25°C.Again, steam is produced when we boil water at 100°C and more than that.Therefore,heat is also a type of energy.So,particle in steam at 100°C have more energy than water.

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.


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