classification of matter
state of matter
The form of substance is divided into three namely solid, liquid and gas.
a. Solids
The objects around you, such as earth, rock, wood, metal, and books include solid clusters. You can certainly specify an object including a solid object or not. Every object that is in solid form is always fixed.
b. Liquid
Water, oil, milk, and soy sauce belong to the liquid. Liquids follow the shape of the container. The always flat nature of the water surface The properties are utilized by the builders in ensuring that the height of the walls in a building has been completely flat. The nature of the next water, which is moving in all directions from high to low place. Other water properties are pressing in all directions. The nature of the water will flow out the tube.
c. gas
Air and smoke are objects that belong to gas objects. In contrast to solid and liquid objects, the gas is difficult to observe. Air is a gas that can not be seen. However, we can sense its existence.
Pure substances
Pure substance contains only one kind of constituent substance. Pure substances have certain properties which are always the same, such as pure water which always has a melting point or melting point of 0oC and a boiling point of 100 ° C at atmospheric pressure 1.
Examples of pure substances
(A) carbon,
(B) copper,
(C) gold,
(D) iron,
(E) lead,

Explain about difference of solid,liquid and gas
BalasHapusefinition of Solid
HapusBy the term ‘solid’ we mean the type of matter which is rigid in structure and opposes the change in its shape and volume. The particles of a solid are tightly bound and well-arranged in a regular pattern, which does not allow the particles to move freely from one place to another. The particles continuously vibrate and twist, but there is no motion, as they are too close to each other.
As the intermolecular attraction is maximum in solids, and because their shape is fixed, and the particles stay, where they are set. In addition to this, the compression of solid is very tough, as the spaces between molecules are already very less.
Definition of Liquid
A free flowing substance of constant volume having consistency is called as the liquid. It is a type of matter which do not have its shape but takes the shape of the vessel, in which it is held. It contains small particles, which are held tightly by intermolecular bonds. One of the unique property of liquid is surface tension, a phenomenon which makes the fluid possess the minimum surface area.
The compression of liquid is a nearly difficult, due to less gap between particles. The particles are closely bound, but not as tightly as in the case of solid. Thus allowing the particles to move around and mix with one another.
Definition of Gas
Gas is described as a state of matter which diffuses freely in all directions and fills the entire space available, regardless of the quantity. It is made up of particle that does not have a certain shape and volume. The particles can be individual atoms or elemental molecules or compound molecules.
In gases, the molecules are loosely held, and so there is a lot of space between molecules to move freely and constantly. Due to this characteristic, the gas has the ability to fill any container, as well as it can be easily compressed.
What are the different elements and compounds?
BalasHapusAll matter is made from atoms. Atoms are very, very small. A molecule is formed when atoms join together by chemical bonds.
HapusThere are over a hundred different types of atom, called elements. The atoms of a particular element are identical to each other. They cannot be changed chemically into any different element. For example a piece of pure sulfur consists only of sulfur atoms. No chemical process can break it down into a different substance.
Compounds are substances that contain atoms of at least two elements chemically combined. For example: magnesium oxide consists of magnesium atoms and oxygen atoms chemically bonded together.
Water mixed milk including homogeneous or heterogeneous?
BalasHapusHeterogeneous mixtures are non-uniform solutions that can be separated into two (or more) individual substances by physical means (homogeneous mixtures cannot be).
HapusA glass of ice water is a heterogeneous mixture because we can easily separate the ice from the liquid water by filtration.
With milk, you have white particulates that give a non-uniform solution, so it is heterogeneous.
Whether all metals including solids.?
BalasHapusNo, for example mercury
HapusWhat is the process of changing the form from solid to gas without experiencing liquid phase?
BalasHapusSolid To Gas: Sublimate
BalasHapusThe transformation of a solid object into a gas object.
For example: Mothballs stored in the open for a long time run out.
