Question

16. A few substances are arranged in the increasing order of 'interparticle spaces. Which of the following represents a correct arrangement? (a) Gold, ethanol, nitrogen (b) Water, iron, oxygen (c) Aluminium, hydrogen, glycerine (d) Carbon dioxide, methanol, copper​

Answer 1

Answer:

• The space between atoms in solids, liquids and gases are called as “inter-particle space”.
• It is completely depends upon the state of the substance. If substance is present in the solid state the inter-particle space is very less.
• If substance is present in the liquid state the inter-particle space is ‘high’ than compared to the solids.  
• If substance is present in the gaseous state the inter-particle space is ‘very high’ than compared to the liquids.  

The following increasing orders of given substances represents the correct arrangement of inter-particle space between particles as follows:

(a) Gold  < ethanol < nitrogen  

(b) Iron < Water < oxygen  

(c) Aluminium < glycerine<  hydrogen

(d) Copper < Methanol < Carbon-dioxide

Answer 2

Option A is right answer

$Gold < ethanol < nitrogen$

The following increasing orders of given substances represents the correct arrangement of inter-particle space between particles as follows:

(a) Gold < ethanol < nitrogen

(b) Iron < Water < oxygen

(c) Aluminium < glycerine< hydrogen

(d) Copper < Methanol < Carbon-dioxide
