Question

The melting point of two solids is 300K and 400 K respectively .Which has more
intermolecular force of attraction .Why?

Answer 1

Answer:

Intermolecular forces are the forces which mediate an interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions. Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together.

The molecules having high melting points will have high intermolecular forces and hence the order of intermolecular forces is X<Y<Z

hope it's help you!!!

Answer 2

Answer:  

Explanation:

1 400 2 because it has large intermolecular force 4 because it has a value of 2260 5 because it in surface area we can dry our clothes by increasing surface area 7because it is used in breaking the force of attraction
