Avogadro’s Law When applied to gases, Avogadro’s law (also known as Avogadro’s principle or Avogadro’s hypothesis) states that the total number of atoms or molecules in a gas (that is, the amount of gaseous substance) is directly proportional to the total volume occupied by the gas at constant temperature and pressure. Avogadro’s law is closely […]

Emulsion is a mixture of two or more liquids having minute or ultramicroscopic droplets dispersed through one another, as defined in physical chemistry. Either spontaneously or mechanically, (such as agitation) emulsions are created from the liquid components, provided that the liquids being mixed have no or minimal mutual solubility.  Emulsions are commonly used in several

Gas laws are a group of physical principles that predict the behaviour of gases. Many of those laws pertain to ‘ideal’ gases in closed systems at degree Centigrade and pressure (STP). However, their concepts should be used to understand and influence the spread of physical and chemical processes within the body. Every application of gas

Colloids are mixtures of chemically microscopic components that are insoluble in nature and the particles of one substance are dispersed into another substance. The particles that are suspended in a colloidal mixture can vary between one to one thousand nanometers. For a mixture to be categorised as a colloid, the particles that are dispersed into

Introduction An Antiseptic is a chemical agent or substance which is applied to the external body skin to slow or stop the growth of the microorganisms and to prevent any kind of infection. They are basically used in hospitals and medical institutions to reduce the chances of infection during performing any kind of surgery or

What exactly are Alcohol? Alcohols are molecules with one or more hydroxyl groups attached to aliphatic carbon atoms, whereas phenols have one or more hydroxyl groups attached to aryl carbon atoms. A hydroxyl group can be found in any type of alcohol. Some alcohols have several practical applications in everyday life. Various Types of Alcohol

Band theory is a method that calculates the energy gap in electrons of a specific solid to separate two kinds of bands, namely Valence bands and Conduction bands. Any solid can be classified among Conductors, Semiconductors, and Insulators based on its properties. Contrary to the discrete energy of free atoms, the quasi-visible bands are the
