Introduction The Frenkel Defect is a flaw in the production of lattice crystals in which an ion or perhaps atom occupies a normally unoccupied position. It is called after Russian physicist Yakov Frenkel. The vacancy in the crystal is generated by the voluntary spacing out of 1 atom. This defect is sometimes known as a dislocation defect since it exhibits both valencies as well as self-interstitial faults. Small cations in the crystal lattice are displaced from their original places, resulting in an empty site in the crystal lattice. Formation of Frenkel Defect The following is how the mentioned defect forms ... Read More

Introduction Fossil fuels are hydrocarbon (combination of carbon and hydrogen)- containing substances formed naturally (in nature) on the surface of the earth (earth’s crust). They are formed from the remains left-over) of dead (not alive) plants (flora) and animals (fauna) that are extracted (being absorbed) and buried under the soil and burned as fuel. Some of the known and widely used fossil fuels (or, fuels) are coal, petroleum, and natural gas. Coals are formed as rock strata (stone) called coal (charcoal) seams. Coal is produced (formed) when the dead (not alive) plant matter (flora) decays (decomposed) into peat (accumulation of ... Read More

Introduction Formaldehyde is a natural chemical molecule that is both highly poisonous and carcinogenic. The pure form of formaldehyde, which is a strong-smelling, colourless gas that spontaneously polymerizes into paraformaldehyde, is kept in an aqueous solution form called formalin that is also used to preserve animal specimens. The chemical formula of formaldehyde is CH2 O. Structure of Formaldehyde When pure, formaldehyde is a colourless gas with a potent odour. The simplest aldehyde, formaldehyde, is synthesized as well as produced naturally by people, animals, and plants. A significant source of organic molecules necessary for life is formaldehyde. Formaldehyde is a ... Read More

Introduction Food chemistry refers to all the chemical processes occurring in food. It majorly focuses on the composition and functional properties of foods and food products during various stages. Though food serves essential nutrients like proteins, carbohydrates, fats, vitamins, lipids, and minerals. It should be made sure to have food with the necessary nutrients. Food is produced from sources like plants or animals. This food provides abundant energy to the body due to its biological action. For example, sugar, a simple form of carbohydrates, is broken down by the body during respiration, it converts into the form of energy. ... Read More

Kelvin Scale

Introduction The Kelvin or the kelvin scale is denoted or represented by the symbol K, it is the S.I. unit of temperature (T). It is an absolute (abs) thermodynamic (td) temperature (T) scale, which means it uses absolute zero (0) as its null or zero point. The mathematical formula relating the Celsius and the kelvin scale is- K=°C+273 or, T(K)=T(°C)+273. We can convert this kelvin scale to any other scale and vice-versa using the following formula- (K-273)/100=C/100=(F-32)/180=R/80. The Fahrenheit scale (s) is also a temperature (T) scale. Its S.I. unit is degrees Fahrenheit, and it is denoted by the symbol ... Read More

Kelvin Scale and Celsius Scale

Updated on 20-Mar-2024 11:49:12

Introduction The process of measuring temperature is very important for getting information related to a local region. And this can then be used for an immediate evaluation. There are many discoveries for the making of a proper temperature measurement scale. The device first introduced for the measurement of temperature was the thermoscope. Gabriel Fahrenheit produced the first thermometer in the 18th century, it is a mercury-based one. The Fahrenheit scale is the measuring scale and is still in use. The discoveries further continued for a proper scale for measuring the temperature. Later Anders Celsius introduced the Celsius scale in 1972. ... Read More

Introduction Potassium sulphate is an inorganic compound with the other name sulphate of potash is an important chemical compound with many applications, especially in fertilizers. In the 14th century itself, potassium sulphate was known. Tachenius, Glauber, and Boyle are the first to study this chemical compound. It is a salt that is a combination of an acidic and basic compound. Christopher Glaser, a pharmaceutical chemist prepared it and used this for chemical applications, making it named Glaser's salt. It is especially a synthesized chemical, the mineral form is very rare, and arcanite is the mineral of potassium sulphate. A ... Read More

J J Thomson's Atomic Model and Its Limitations

Praveen Varghese Thomas
Updated on 20-Mar-2024 11:53:08

Introduction British researcher J.J. Thomson revealed that the atom was made up of many tiny components designed to transport electrical charge. During Thomson's study, scientists believed that atoms were fundamentally neutral. Thomson claimed that atoms included microscopic -ve particles floating over a +ve charged fluid. The plum pudding model is another name for this model. What do we understand by an Atomic Model? The atomic model is the framework that describes the composition & structure of the atom, and it has evolved over the years. The atom has been extensively studied as a constituent of the cosmos to comprehend ... Read More

Isothermal Expansion

Updated on 20-Mar-2024 11:55:09

Introduction An isothermal process is a type or form of the thermodynamic process where the temperature (T) of the system (s) remains constant (c), that is ΔT=0. This process occurs generally when the system remains in contact with an outside (o) thermal reservoir, and also a change in the system (s) occurs slowly (s) enough to permit the system to be continuously adjusted or fixed to the temperature (T) of the reservoir through the heat (ΔH) exchange. For an ideal gas, all the collisions between (b/w) molecules or atoms (a) are perfectly (completely) elastic and there is no intermolecular ... Read More

Introduction Butane is a saturated hydrocarbon with four carbons. It is unbranched in structure. It is a type of organic chemical. Its chemical formula is C4 H10. It is a widely utilised chemical that is mostly utilised in gasoline mixtures. It is sometimes referred to as Methyl Ethyl Methane or even n-Butane. It belongs to the paraffinic hydrocarbon family. It is an organic chemical that, at ambient temperature as well as atmospheric pressure, is a colourless, extremely combustible gas. It smells like gasoline. What are Isomers? Isomers are substances that have a similar no. of atoms, that is, ... Read More
