State of matter
From CreationWiki, the encyclopedia of creation science
There are three main states of matter which are known as solid, liquid and gas, including the physical changes. Another term for states of matter is known as a physical state which is often described as a phase. A phase is basically a set of a physical system that have a correct composition and properties of a physical state. Usually people are confused between a physical state and a phase.

Solids
A solid has a define shape, volume, and density. Solids make up the shape of whatever container it may be in or the object. Solid particles are close together which makes them vibrate against each other. A solid is difficult to form by hand and squeeze by pressure into a smaller volume. If heated, solids will expand by a little bit; a solid has a definite shape and a definite volume.
Liquid
The particles in liquid matter are close to each other, however the arrangement of the particles in a liquid is not as orderly as a solid matter. The reason for this is that liquids are free to flow around each other from one location to another. Liquid matter forms the shape of the container that is given. However, even if the liquid forms to the shape of a container, the volume doesn't necessarily change. The volume of the liquid is fixed or constant, meaning that the liquid forms in a type of vaporization at a certain temperature by a definite amount of pressure. Liquids are unyielding to pressure or force, but when they are heated they tend to expand slightly.
Gas
Gases have a indefinite shape and volume and are easily compressed to form the shape of the container. Gases are similar to liquids because they form the shape that a container is formed. The particles for a gas have a wide difference apart from liquid particles. They are farther apart from each other which tends to go all over the place. Since the particles are widely apart, the space between gases is easily pressed together into a smaller volume. Another word that can be used as gas is called vapor. The word vapor and gas are used exchangeably from time to time. However, there are differences between the two words. Gas is used when we describe substances such as oxygen, that forms at a gaseous state of room temperature. A visible exhalation, known as vapor, mainly gives an explanation about the state of a substance in a gaseous atmosphere usually in a liquid or a solid at a room temperature.
Physical Changes
Physical changes doesn't necessarily mean the change of nature but rather the change of their physical properties. A physical property can be seen without the change from the type of matter. Another way we can see or observe an physical property would be texture, shape, size, color, odor, volume, mass, weight, and the density of the object. These are some of the things you may observe throughout a physical change.[1]
History
In the year of 1924, Albert Einstein and an Indian physicist Satyendra Nath Bose predicted that the condensation happens when the atoms change into an atom known as the "superatom". That is why this new idea or theory was known as the Bose-Einstein Condensate. Throughout the 71-year study of this theory, it was confirmed by many other physicist for the search of the mythical Holy Grail. This particular theory allows scientists to study the strange and unique world of physics as if they were searching or observing through a huge magnifying glass.[2]
