Can you explain the answer of this question below:Practice Test/Quiz or MCQ (Multiple Choice Questions) with Solutions of Chapter "Matter in our surroundings" are available for CBSE Class 9Science and have been compiled as per the syllabus of CBSE Class 9ScienceQ. Which of the following has the strongest interparticle force at the room temperature?A:NitrogenB:MercuryC:IronD:ChalkThe answer is C.

Question

Answer

Interparticle Force

Interparticle force is the force of attraction or repulsion between particles of matter. The strength of this force depends on the nature of the particles involved and the temperature of the substance.

Strongest Interparticle Force

Out of the given options, iron has the strongest interparticle force at room temperature because of its metallic bonding. Metallic bonding is the force of attraction between positively charged ions and negatively charged delocalized electrons that surround them.

Mercury has weaker interparticle forces because it is a liquid at room temperature and has weaker metallic bonding due to its smaller size compared to iron. Nitrogen has weaker interparticle forces because it is a gas at room temperature and has weaker van der Waals forces between its molecules. Chalk has weaker interparticle forces because it is a solid made up of covalently bonded molecules with weak van der Waals forces between them.

In conclusion, the strength of interparticle forces depends on the nature of the particles involved and the temperature of the substance. Iron has the strongest interparticle force at room temperature because of its metallic bonding.

Answer

It is because iron is solid and solid have highest inter particle force among them

Answer

Solid has the strongest intermolecular forces then nitrogen Mercury and chalk in room temperature ad the melting point of iron is high.

Answer

The melting point of iron is considerably high, so the interparticular force is high in iron...

Answer

As we know, Higher the melting point of a substance, geater will be the force of attraction between it's particles. The melting point of iron metal is 1535 degree celcius , so the force of attraction between it's particles is higher..

Answer

C

Answer

C. iron

Answer

Because iron is a solid and have a huge intermolecular force.

Answer

Iron is solid at room temperature because it's particles closely packed

Answer

The temperature at triple point of water is

Answer

Iron is a solid substance which has high intrmolecular force.

Answer

Because iron is a solid and it has highest intermolecular forces than other options
