Correct Answer – 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.

Correct Answer – B
At low temperature existence of a substance in solid state is due to
(a) slow molecular motion and
(b) Strong cohesive forces
These two forces hold the constituent particles together thus causes existence of substance in solid state.

Correct Answer – B
At low temperature, molecular motion are slow, thus contituents are close together. Moreover , strong cohesive forces also holds the costituents together. These two conditions shows the existence of a substance in solid state.

Correct Answer – B
At sufficiently low temperature, the thermal energy is very low. The constituent particles are so close that they have hardly any translatory motion. The substances exist in the solid state.
