Arranging the substances in order of increasing density:
1. Air: Compared to these substances, air has a relatively low density. It has low density due to the gaseous molecules that make it up.
2. Exhaust from chimneys: Chimney exhaust density can change, and it depends on mixture. It is normally comprised of gases, such as carbon dioxide and nitrogen with higher density than air.
3. Cotton: Cotton is a solid with a relatively low density. This has lower density than other denser materials owing to its fibrous and porous nature.
4. Water: Water has a moderate density. At a state of ordinary temperature, its density is roughly 1g/ cm3 which makes it denser than either air or a cotton.
5. Chalk: Water usually has a lower density than chalk. It is either more dense or less dense than water depending on the composition (mostly contains calcium carbonate).
6. Iron: Iron is considerably denser than all other materials in this list. It weighs about 7.87 g/cm3, which means it weighs heavier than water, chalk, cotton, chimney exhaust and air.
So, the substances arranged in order of increasing density are: air, smoke from chimnies, cotton, water, chalk, and iron.
All solid, liquid, or gas is defined by its unique characteristic traits among these fundamental states of matter. This is because solid molecules possess tightly-packed particles that vibrate with very less mobility but maintain shape and volume, hence rigidity and no flow ability. ``` ContributionRead more
All solid, liquid, or gas is defined by its unique characteristic traits among these fundamental states of matter. This is because solid molecules possess tightly-packed particles that vibrate with very less mobility but maintain shape and volume, hence rigidity and no flow ability. “` Contribution: However, such individuals have a tendency of having their hands and legs crossed behind them in a closed position. Solids show minimal volume change but adopt a shape similar to the container while liquids remain definite volume but assume some of the container’s features while fluids are completely fluid. Unlike gases that do not have specific shape or volume; dispersed particles, which moves freely within it, results very low rigidity and a lot of fluidity. Compressibility of solids and liquids is lower than that of gases because the particle distance is great. Gases take all the available space and solids as well as some liquids do not fully occupy their containers. Particles are close with solid densities being high while gas densities are low, reflecting particle arrangements and spacings. This is because the characteristic features show how the states differ and exhibit their peculiar behavior and inherent qualities under normal or special situations.
1. Rigidity: Particles of a solid substance pack very close together leading to more rigidity and fixed shape. The liquid has the least stiffness due to the movement of particles past one another, making it possible for the liquid to assume the shape of the container. Gases are very flexible since tRead more
1. Rigidity: Particles of a solid substance pack very close together leading to more rigidity and fixed shape. The liquid has the least stiffness due to the movement of particles past one another, making it possible for the liquid to assume the shape of the container. Gases are very flexible since their particles keep on moving freely throughout the available spaces.
2. Compressibility: Due to tightly packed solid particles, solids are usually incompressible. Secondly, liquids are not well compressible. Despite that, gases can be considered compressible since their particles are relatively distant, which readily allows their compaction within smaller volumes.
3. Fluidity: Solid has very little fluidity because of movement in its particles is limited. Liquids have a great degree of fluidity because particles can move about in them and assume the shape of the container. The particle movements in gases are fast and random, making gases extremely fluid.
4. Filling a gas container: The solids are in rigid shapes and volume thus occupy little space in the container. They keep a fixed volume, however they adopt the shape of the container. The gases have no definite shapes or volumes, hence, filling up the space of the container they occupy until all space is filled.
5. Shape: Solids have a shape which is not determined by a container; therefore, it has its own form and does not change despite the container. However, liquids conform to the shapes which their containers possess, but exhibit certain volumes. In this case gases have a shape and volume determined by the container in which they are present.
6. Kinetic Energy: The particles are only mobile and therefore have less kinetic energies in solids than liquids. The particles of liquids move more freely than a solid and therefore exhibit moderate kinetic energy. This is because gases have the highest kinetic energy, whose particles move fast and arbitrarily.
7. Density: The solids has a relatively large density because of the close packing of its particles. Liquids have moderate density. Because of wide separation of their particles, gases have a low density.
As its characteristic is high compressibility and low intermolecular forces, a gas fills entirely the vessel where it is stored. Gas particles are far apart with more kinetic energy that allows them to separate from one another. The gas’s particles quickly spread out in all directions when they areRead more
As its characteristic is high compressibility and low intermolecular forces, a gas fills entirely the vessel where it is stored. Gas particles are far apart with more kinetic energy that allows them to separate from one another. The gas’s particles quickly spread out in all directions when they are placed inside the container, hitting the container’s walls and each other.
Gases do not have fixed shapes or volumes, hence total filling of the vessel. They fill up all the space they find and adopt the form of the receptacle. Gas molecules are very mobile and travel throughout a space randomly until their pressure is equal in every direction, at which point they would fill throughout a vessel.
Moreover, gases are highly compressed and hence they are very compressible thereby making them easy for packing into small volumes. In this way, they can squeeze into whatever space that is available as a gas will always tend to fill its containing container irrespective of its size or shape.
The mass per unit volume of a substance is called density. (density = mass/volume). Arrange the following in order of increasing density-
