Molecular compounds tend to have the lowest melting points.
it is an amorphous solid
Yes, in general, the lowest energy state of a system tends to be more stable because it represents a state where the system has achieved a balanced and minimally energetic configuration. Systems naturally tend to move towards their lowest energy state to increase stability and minimize energy.
Because although the covalent bonds between the elements are strong, there are only weak forces between the molecules so they have low melting points
Ionic compounds tend to have high melting and boiling points due to the strong electrostatic forces between ions. In contrast, molecular compounds composed of nonmetals tend to have lower melting and boiling points due to weaker intermolecular forces such as van der Waals forces.
Boron is a nonmetal that can react with certain elements, particularly metals, to form borides. It tends to form strong covalent bonds and can react with metals like aluminum, magnesium, and titanium to create borides with high melting points and hardness. Boron is also known to form stable compounds with oxygen, such as borates.

it tends to not form crystals
Generally, as the carbon chain length increases, the melting point of a compound also tends to increase. This is because longer carbon chains result in stronger intermolecular forces, such as London dispersion forces, leading to a higher melting point. Shorter carbon chains have weaker intermolecular forces, so they typically have lower melting points.
the freezing point is 0 degrees celsius and the melting point is is above 0 degrees celsius
Impurities decrease the melting point of water by interfering with the crystal lattice structure. Pressure can increase the melting point of water by stabilizing the solid form due to the reduced volume and increased interactions between molecules. Overall, impurities tend to lower the melting point, while pressure tends to raise it.
When more valence electrons of a metal are shared, the metallic bonding becomes stronger, leading to a higher melting point. This is because the increased delocalization of electrons throughout the metal lattice requires more energy to break the bonds in order to melt the metal.
It is in a solid state of matter. Unlike the deeper rocks of the mantle, crustal rocks do not readily deform, and heating from below will cause the lowest layers to melt into magma...which being less dense tends to flow upward.

Slate splits into sheets and is used on roofs.
There are multiple Black Rods, but on the whole they are a shaft of black ebony, topped with a silver crown with some other decorations at points of the shaft. The bottom tends to have a solid base as it is used to bang on the doors of the lower house at the opening of parliament.
About 1-3 in the stomach. In the intestinal tract it tends to be near physiological pH (7.4).
No. The mantle tends to be soft and ductile due to extreme heat. The mantle is constantly melting and mixing with itself, while the description of a mineral states: A mineral is a naturally occurring solid with a highly ordered atomic arrangement and a definite (but not fixed) chemical composition. It is usually formed by inorganic processes.
