Answer 1

Dear student,
a. Freezing point- is a temperature where there is a phase transition where a liquid turns into a solid.
b. Boiling point- is a temperature where there is a phase transition where a liquid turns into a gaseous state.
c. Condensation point- is a temperature where there is a phase transition at which vapour (GAS) condenses into a liquid without any change.
d. Sublimation point- is a temperature where there is a phase transition where a solid directly changes into a gas without undergoing the liquid state.
