Question

why are the melting and boiling point of the same substance different?
pls answer correctly ​

Answer 1

Answer:

This is when they become a liquid. So the melting point is the temperature at which molecules in a solid can move past each other and form a liquid. ... The boiling point is the temperature at which the gas from the liquid is pushing the air with the same force the air is pushing back.

Answer 2

${ \star{ \underline{ \underline { \sf \red{ AnswEr:- }}}}}$

the melting point is the temperature at which molecules in a solid can move past each other and form a liquid. The boiling point, on the other hand, involves liquids and gases. As liquid molecules are moving around, some molecules at the surface of the liquid are escaping.
