Question

Match the items of column I to those of column II.

Column 1	Column 2
Melting point of ice	212$°$ F
Matter with weakest inter-particle forces.	Unit of pressure
Litre	273 K
Boiling point of water	Unit of volume
Pascal	Gaseous state

Answer 1

(A) Melting point of ice - (iii) 273 K

• The melting point is the temperature at which a solid turns into a liquid. The melting point of ice on the Kelvin scale is 273 K.

(B) Matter with the weakest inter-particle forces - (v) Gaseous state

• Gaseous particles are loosely packed and there are the weakest inter-particle forces.

(C) Litre - (iv) Unit of volume

• Litre is the unit of volume.

(D) Boiling point of water - (i) 212$°$ F

• Water boils at 100 °C which is equal to 212 °F

(E) Pascal - (ii) Unit of pressure

• Pressure is the amount of force applied perpendicular to the surface of an object per unit area.
• The SI unit for pressure is the pascal (Pa), equal to one newton per square meter (N/m², or kg·m⁻¹·s⁻²).
