The attractive forces between the molecules in E-stilbene must be stronger than the attractive forces holding Z-stilbene together. The degree of attraction between molecules in a substance always accounts for its state of matter at a given temperature.

Liquid.
Solid
it is a gas
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
change of a liquid to a solid
A gas is not a liquid or a solid.
Whether the solid will float or sink in a solid-liquid mixture depends on the relative densities of the solid and the liquid. If the density of the solid is greater than that of the liquid, then the solid will sink. If the density of the solid is less than that of the liquid, then the solid will float.
Ice is a solid and when melted it turns into a liquid freeze it again and it is solid
the process of passing from a solid to a liquid is liquification but the passage from liquid to solid ist solidification
That depends on the relative densities of the solid and the liquid. If the solid is denser than the liquid, the solid will sink. If the liquid is denser, the solid will float.
