which of the following favours the existenence of a substance in the solid state ?

A

high temperature

B

Low temperature

C

High thermal energy

D

Weak cohesive forces

Text Solution

Verified by Experts

The correct Answer is:
B

At sufficiently low temperature , the thermal energy is low and intermolecular forces bring the particles so close that they cling to one another and occupy fixed positions. The particles can still oscillate about their mean positions and the substance exists in solid state.
