What is melting point and boiling point ?what is condensation? What is latent heat ? What is dry ice? Define clearly in simple language!

Answer 1

Dear student, Boiling point is the temperature at which vapour pressure of the gas escaping from the liquid gets equal to external pressure or atmospheric pressure. Melting point – It is the temperature at which solid melts to become a liquid. At this temperature both solid and liquid phase coexist. Post other query in different thread. Regards
