Question

Study the following graph and fill in the blanks.

	X		Y			P	Q
(A)	Liquid		Gas			Freezing point	Melting point
(B)	Biling		Melting			Boiling Point	Melting point
(C)	Fusion		Vaporisation			Melting point	Boiling point
(D)	Evaporation		Vaporisation			Fusion	Boiling

• A. A – Freezing point, B – Boiling Point, C – Melting point, D – Fusion
• B. A – Melting point, B – Freezing point, C – Boiling point, D – Vaporisation
• C. A – Evaporation, B – Fusion, C – Liquid, D – Gas
• D. A – Vaporisation, B – Fusion, C – Melting, D – Boiling

Answer 1

: X represents melting of solid into liquid and P being the melting point. Y represents vaporization of liquid into gas and Q represents boiling point of the liquid.
