Question

(a) Solids	(i) Can flow in all direction
(b) Sublimation	(ii) The temperature at which a liquid changes into its gaseous state
(c) Boiling point	(iii)Can have any number of free surfaces.
(d) Gases	(iv)Gaps between particles
(e)Intermolecular space	(v)Change of state directly from solid to gas.

Answer 1

(a) Solids - (iii)
Solids have infinite no of surfaces because it has infinite no of shapes and molecules are closely packed to each other and are not able to flow like fluids
(b) Sublimation - (v)
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage.
(c) Boiling point - (ii)
The boiling point of a liquid is the temperature at which its vapor pressure is equal to the pressure of the gas above it.
(d) Gases - (i)
Weak intermolecular forces as compared to the high average kinetic energy the molecules possess is what makes the gas flow easily in all directions, as they have more kinetic energy .
(e) Intermolecular space - (iv)
The space between any two consecutive molecules of a substance is called intermolecular space
