STATES OF MATTER CHEMISTRY PDF

The different states of matter have long confused people. The ancient Greeks were the first to identify three classes (what we now call states) of matter based on. The main difference in the structures of each state is in the densities of the particles. Solids. In a solid, particles are packed tightly together so they are unable to move about very much. Liquids. Gases. Plasma. Bose-Einstein condensates. Melting and freezing. Sublimation. Vaporization. States of Matter. Gases, liquids and solids are all made up of microscopic particles, but the behaviors of these particles differ in the three phases. The following.

States of Matter

The particles of a solid are already so tightly packed together that increasing pressure will not compress the solid to a smaller volume. Solids ] Liquids In the liquid phase, the particles of a substance have more kinetic energy than states of matter chemistry in a solid.

The liquid particles are not held in a regular arrangement, but are still very close to each other so liquids have a definite volume. Liquids, like solids, cannot be compressed.

Particles of a liquid have just enough room states of matter chemistry flow around each other, so liquids have an indefinite shape.

A liquid will change shape to conform to its container. Force is spread evenly throughout the liquid, so when states of matter chemistry object is placed in a liquid, the liquid particles are displaced by the object. Liquids ] The magnitude of the upward buoyant force is equal to the weight of the fluid displaced by the object.

This states of matter chemistry of buoyancy was discovered by the Greek mathematician Archimedes who, according to legend, sprang from his bath and ran naked through the streets shouting "Eureka! This cohesive force pulls the particles together to form drops or streams.

Scientists reported in April they had created a bizarre state of matterone that had been predicted to exist but never seen in real life. Though this type of matter could be held in one's hand as if it were a solid, a zoom-in on the material would reveal states of matter chemistry disorderly interactions of its electrons, more characteristic of a liquid.

In the new matter, called a Kitaev quantum spin liquid, the electrons enter into a sort of quantum dance in which they interact or "talk" to one another.

Matter: Definition & the Five States of Matter

Usually when matter cools down the spin of its electrons tends to line up. But in this quantum spin liquid, the electrons interact so that they states of matter chemistry how the others are spinning and never align no matter how cool the material gets.

Gases Gas particles have a great deal of space between them and have high kinetic energy.

If unconfined, the particles of a gas will spread out indefinitely; if confined, the gas will expand to fill its container. Diagram of particle arrangement and movement Solids The table shows some of the properties of solids and why they are like this.

Even though the states of matter chemistry state changed, the chemical properties were the same.

On the other hand, a chemical change would build or break the states of matter chemistry bonds in the water H2O molecules. If you added a carbon C atom, you would create formaldehyde H2CO.

If you added an oxygen O atom, you would create hydrogen peroxide H2O2. Neither new compound is anything like the original water molecule.

Generally, changes in the physical state do not lead to any chemical change in compounds. Oceans, lakes, and rivers are good examples of liquid water H2O.

Planetary scientists are looking for other planets that have liquid water, but states of matter chemistry require very specific conditions to have water as we know it. Solids in Ceramics Ceramic bowls are a great example of a solid.

When the change of state occurs in stages the intermediate steps are called mesophases.
