Physical and Chemical Properties

Physical and Chemical Properties

All substances have got properties that people can use to recognize them. For instance we can easily identify an individual by their voice, their face, finger prints, DNA and height. The much more of these properties that we are able to identify, the better we all know the person. In a comparable way matter provides properties and you can find many of them. You can find two basic forms of properties that we could associate with matter. These types of properties are known as Physical and Chemical properties: Physical properties: Properties which do not modify the chemical character of matter and Chemical properties: Properties which do alter the chemical nature of the matter.

Samples of physical properties tend to be: smell, color, boiling point, freezing point, infra-red spectrum, melting point, opacity, attraction or repulsion to magnets, density and viscosity. Samples of chemical properties are: reactivity with water, heat of combustion, electromotive force and PH. The more properties we could identify for any substance, the better we understand the nature of that substance.


  

Physical and Chemical Changes

A physical change within a substance does not change exactly what the substance is. In the chemical change in which there is actually a chemical reaction, a brand new substance is created and energy is possibly absorbed or given off. You can find a number of differences between a physical and chemical change within substances or matter. For instance, in case a piece of paper is cut up into tiny pieces still it is paper.

Physical and Chemical Changes


This could be a physical change within the size and shape of a paper. When the identical piece of paper is actually burned, it is split up into various substances which are not paper. Physical changes could be reversed, chemical changes can not be reversed with all the substance altered back without having extraordinary means, if whatsoever. For example, a mug of water could be frozen when cooled then can be came back to a liquid shape when warmed up.

Physical and Chemical Properties of Matter

We all have been surrounded through matter on a regular basis. Something that we touch, use, eat, and so on. Is actually an example of matter. Matter could be described or defined like something that occupies space and it is also made up of miniscule particles known as atoms. It has to display both properties of inertia and mass. physical and chemical properties of matter are: Physical properties are the ones that could be observed without altering the identity of a substance. The common properties of matter for example density, color, hardness, are samples of physical properties. Properties that explain the way a substance changes into a totally different substance are known as chemical properties. Flammability and oxidation/corrosion resistance are samples of chemical properties.

The distinction between a physical and chemical property is actually straightforward before the phase of the material is recognized as. Whenever a material changes through a solid to some liquid with a vapor it appears like them turn into a difference substance. But, each time a material melts, vaporizes, solidifies, sublimes or condenses, just the state with the substance changes.

Physical and Chemical Properties of Oxygen

Oxygen is the initial element inside Group 16 from the periodic table, called the chalcogen family. Arriving from the Greek term chalkos, chalcogen signifies ore. Oxygen and sulfur, the initial two elements from the chalcogen family are located in many ores. The physical and chemical properties of oxygen are: Oxygen is available in all three forms, solid, gas and liquid. The solid and liquid types are a light blue colour. But, oxygen gas is actually odourless, tasteless and colourless. The elemental structure is actually a cubic crystal form. Oxygen are present in every three allotropic forms. These allotropic forms contain diatomic oxygen, dioxygen or normal oxygen,; nascent, monatomic or atomic oxygen; and triatomic oxygen or ozone. Oxygen is an extremely reactive element, very paramagnetic and is readily capable of mixing with other elements.

One of oxygen's most significant chemical properties is always that it helps combustion. Oxygen additionally combines together with elements in room temperature, for instance, the development of rust. Decaying is a good example of oxygen responding with compounds. Water and carbon dioxide would be the principal products of decay.
