Question

Defination of latent heat of fusion and melting point, sublimation

Answer 1

$<h2> hey DUDE </h2>$
ʟᴀᴛᴇɴᴛ ʜᴇᴀᴛ ᴏғ ғᴜsɪᴏɴ :- it's the heat required to convert solid of the given mass into liquid at atmospheric pressure at it's melting point without causing any change in it's temperature.

ᴍᴇʟᴛɪɴɢ ᴘᴏɪɴᴛ :- melting point is the stage where a solid starts to melt and get converted in it's liquid state. basically it's the temperature at which the solid starts melting at the atmospheric pressure.

sᴜʙʟɪᴍᴀᴛɪᴏɴ :- it's a process where a solid is directly converted into it's gaseous form without converting into it's liquid state.

Answer 2

LATENT HEAT OF FUSION --->The latent heat of fusion of a solid is the quantity of heat in joules required to convert 1kilogram of the solid to liquid, without any change in temperature.

MELTING POINT---->the temperature at which a substance will melt .

SUBLIMATION---->sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
