Question

What is latent of fussion?

With the help pf a labelled diagram describe an activity to show that nature of matter is particulate and not continuous?

Answer 1

Since you feel difficult understanding above answer, I will give you another simple definition.

Q1)
Latent Heat:- It is defined as the heat required to convert a solid into a liquid or vapour, or a liquid into a vapour, without change of temperature.

Latent Heat of Fusion:- It refers to the phase change between solid and liquid without changing temperature.

Q2)

Take some water in a beaker & note it's level.
Dissolve some salt or sugar in it with the help of a glass rod. The salt dissolves in the water but the level of water doesn't change . This is because the particles of salt get into the space between the particles of water.

Another examples:
take a beaker with water add some salt then taste it , we can taste the salty ness of the salt in water this means the salt is made up of particles which got evenly mixed in the inter particular spaces of water.
another example can be a glass which i appears to be continuous in nature but break it, then we can see that the glass was composed of particles i.e they shed into particles....

hope this helped u...
