Well we have to match the following
(i) Particles moves randomly at high speed .
↓
(b) Nitrogen .
Reason :- The condition written is the the property of gases , And on the other side there is only one gas ( Nitrogen)
Hence (i) → (b)
(ii) Particles can slide over each other .
↓
(c) Ethanol
Reason :- As we know that if the molecules are little tightly packed they can only slide over each other , i.e Cannot move freely in random directions , And as it's a property of liquid so Ethanol is the only liquid on the other side.
Hence (ii) → (c)
(iii) Particles are not free to move
↓
(a) Iron
Reason :- As we know that in solids particles are very tightly packed , which don't allow to move them . And the only solid on the other side is Iron .
Hence (iii) → (a)
