it is probablydiamond.considering how much force it takes to even scratch it even with another diamond,but I'm not a scientist so go on some science site before considering this ancer.
Bread is considered a solid. Solids have a definite shape and volume, meaning they maintain their form and occupy a specific amount of space. In the case of bread, its particles are closely packed together, giving it a fixed shape and volume. This is in contrast to liquids, which have a definite volume but take the shape of their container, and gases, which have neither a definite shape nor volume.
P waves can travel through all types of matter. S waves can only travel through solids.
A two-dimensional representation of a solid figure is known as a net. It shows all the faces of the three-dimensional shape unfolded into a flat surface, allowing you to see how the shape is constructed and visualize its different parts. Nets are helpful for understanding the properties and structure of 3D shapes.
Primary waves (P-waves) are the fastest seismic waves and can travel through all layers of the Earth, including the solid inner core. They are compressional waves that travel by compressing and expanding the material they pass through.
Rocks come in different sizes and shapes because they are formed through various geological processes such as cooling and solidification of magma, weathering and erosion, and pressure and heat deep within the Earth. These processes lead to the formation of rocks with different compositions, structures, and textures, resulting in a wide variety of sizes and shapes.
Shape
For gas and liquid, it took shape of what ever contain them. For solid, it took original shape of what ever contain them before freezing to solid or mold them to solid. The later shape of solid is due to what it suffer over time to shape it to existing shape.
A square I think.
An irregular polyhedron is a solid shape in which either all edges are not the same length, or all faces are not congruent polygons or all [solid] angles are not of the same measure.
A polygon with all sides and all angles equal.
Because a tetrahedron is a triangular based pyramid that has 4 identical faces and 4 faces meet at all the vertices.
A shape refers to the outline or form of an object, such as a circle or square. A solid shape, on the other hand, has three dimensions (length, width, and height) and occupies space, like a cube or sphere. In essence, all solid shapes are shapes, but not all shapes are solid shapes.
Cells can take on a solid shape, have no shape at all, or change shapes.
A polyhedron.
A solid has a definite shape because the particles in a solid are tightly packed together and all fixed into one position to where they can only vibrate.
A solid has a definite shape, and a definite volume.
the difference between the an irregular and regular solids are that an irregular solid has sides that are not even and you cant measuer with a ruler and you can not measuer it exactly. a regular solid you can measure without a problem with a ruler.
