~ it provides limited protection to personnel who cannot wear masks ~it can be implemented more easily than evacuation ~it uses common skills and supplies anyone can learn and practice
Animals could pull wagons of goods farther and faster.
it can easily pass through a wire a conductor or a battery
Slaves who showed a tendency to escape were branded as a means of identifying them. This contributor has seen a slave identification tag, much like a dog tag, used in the United States in the 1800's, but such a tag could more easily be discarded by an escaped slave, whereas the brand was permanent. Also, as the branding hurt immensely, it was probably effective in dissuading escapes and other transgressions.
Solids have a strict shape and volume. Solids do not flow and they are usually cannot be easily compressed.
The question is based on the misconception that liquids and solids cannot be compressed: they can. The molecules of gas are further apart allowing them to be compressed more easily.
The phases that can be compressed are typically the gaseous and vaporous phases of matter. Liquids and solids generally cannot be compressed as easily due to their closely packed molecules.
Solids cannot be compressed easily because their particles are arranged closely together in a fixed position. When external pressure is applied, the particles cannot move closer together, causing the solid to resist compression. However, under extreme pressure, solids can be compressed slightly due to the deformation of their atomic structure.
Liquid and gas can flow and change shape to fit their containers, while solids have a fixed shape and volume. Liquids and gases can also be easily compressed or expanded, which is difficult for solids to do.
In gases, particles are widely spaced and have high kinetic energy, allowing them to be compressed easily. In solids, particles are closely packed and have strong intermolecular forces that prevent compression. This is why gases can be squashed or compressed, while solids maintain their rigid shape.
A substance that cannot be compressed of manipulated easily.
Liquids and solids have particles that are already in close proximity and held together by strong intermolecular forces, making compressing them difficult. In contrast, gases have particles that are far apart and move freely, allowing them to be compressed more easily.
Solids: they have fixed shape and fixed volume. They cannot be compressed much. They cannot flow. They do not fill their container completely. They have high density. They are heavy. Liquids: they have fixed volume but not fixed shape they take the shape of their container. They cannot be compressed much. They can flow. They do not fill their container completely. They have moderate to high density. Gases: they do not have fixed shape and volume. They can be compressed easily. They can flow. They fill their container completely. They have very low density.
Gases can be easily compressed because their particles are far apart and have more space to move closer together under pressure. In contrast, solids and liquids have particles that are already densely packed, so there is limited room for further compression. This is due to the difference in the arrangement and movement of particles in each state of matter.
A solid is a substance that cannot be compressed because its particles are closely packed together in a fixed arrangement. Solid substances also cannot flow, as their particles do not have the ability to move past each other easily.
Liquids and solids are incompressible because their particles are packed closely together in fixed positions that restrict movement. In contrast, gases have particles that are widely spaced and move freely, which allows them to be compressed easily by reducing the volume between particles.
