Different types of solids

-

  Solids are known as the most ordered state of matter, all of the atoms or molecules in the solid are connected othether to form objects with firm and stable shapes.  A solid itself can not change volume, some solids like sponges can be squeeze, but that is only air that are coming out, the solid itself does not change size.


Different types of solids:


Crystalline Solid:

The molecules in a crystalline solid are arranged in a regular pattern, there are strong bonds between atoms and molecules.

Amorphous Solid:
Atoms and molecules are NOT arranged in a regular pattern.  They are more like those in a liquid.

Different properties of solids

Solids may be strong or weak, hard or soft, and may return to their original shape or stay deformed after a force acting on it.  All depends on the molecules and atoms that makes up the solid.

Brittle: Brittle solids (ceramics) can have craks pass easily through it when exposed to stress (vibration, shock).  The atoms connot move to absorb the stress, so it deform and becomes less hard.

Ductile:  Ductile solids (elastic) changes shape when stretched.  When a solid changes shape permanently, is it called a plastic deformation.  A lot of metals are ductile due to the atoms allowing each other to slide over another.

Malleable: Malleable solids can deform when compressed but can also be ductile.  They can be flattened by rolling or hammening.  For example, tire are malleable, they can deform when compressed, and depending on the tire, they can also be stretched.

Everyday application of Hess's Law

  Everyday application of Hess's Law Burning calories, consuming food, driving home, we all should be familiar with these actions because we do them everyday, but what some of us don't realise is that all these actions related one fundamental law of conservation of energy, Hess's Law.   Hess's Law states that: regardless of the multiple stages or steps of a reaction, the total enthalpy change for the reaction is the sum of all changes. [1]   We will further discover how our indrustries, human body and drug production are related to this law and to better understand the science behind it. Industries Today, all our mass and low cost production depends on factories and industries and all these industries require huge amount of energy.   To keep everything the most efficient possible, these industries has to determine the method that is the most effective to produce a product based on the energy needed or released.   For example:  Car companies must determine ho

Antoine Lavoisier and his contribution to Chemistry

The French Bourgeoisie helping out with science: “In performing experiments, it is necessary… that they be simplified as much as possible, and that every circumstance that could complicate the results should be completely removed.” -Antoine Lavoisier Early life and Work: On the 26 of  August 1743, Antoine Lavoisier was born to a wealthy family of nobility and was the son of an attorney at the Parliament of Paris. He  went to school at the College des Quatres Nations, University of Paris at the age of 11 were he studied chemistry, botany, astronomy and mathematics and received a law degree which admitted him the bar. (1). This French nobleman, chemist and biologist is credited for being the first one to put an extensive lists of the elements, helping construct the metric system and reform chemical nomenclature. Lavoisier is also known as the “ father of modern chemistry” (1). Lavoisier who was originally part of the Ferme generale ( most hated components of the F

Are physical properties such as temperature invented or discovered?

TOK Blog Are physical properties such as temperature invented or discovered? Even tho we don’t know exactly how temperature was invented or discovered we know for sure the Galileo Galilei was the first human being that came up with the idea of an instrument able to calculate the temperature know as a thermometer. Many scientist don’t really recognize Galilei’s instrument as a thermometer but, more as thermoscope because his device only showed the change in temperature and had no scale .The measurement of temperature consist of “The process of measuring a current local temperature for immediate or later evaluation.” Celcius In 1742 two years before his death Celcius created a scale which was reversed a 0° represented the boiling point of water and 100° represented the freezing point of water. Kelvin In 1848, William Thomson created the Absolute Thermometric Scale that could measure the absolute zero as the scale's null point, and in which he used the Celsius as
