Green chemistry is a strategy for developing chemical processes and products that reduce or eliminate the use and generation of hazardous substances. In order to prevent the introduction of chemical pollutants into the environment, chemical reactions should be designed so … Read more
The Aufbau principle is a crucial chemistry principle for determining an atom’s electron configuration in its ground state. The Aufbau principle requires the atom to adhere to Pauli’s exclusion principle and Hund’s rule, which states that each orbital can initially … Read more
Helium is the second most abundant element in the universe. Helium is a noble gas and its symbol is He. The elements in Group 18 (VIIIA) of the periodic table are noble gases. It is colorless, odorless, and tasteless. It is monatomic … Read more
One of the most prevalent thermodynamic cycles found in gas turbine power plants or aircraft is the Brayton cycle. There are two broad categories of thermodynamic cycles: power cycles, which generate a net power output, and refrigeration and heat pump … Read more
A heat engine draws heat from a source and uses it to create mechanical work for a variety of purposes. For instance, a steam engine on an antique train can generate the necessary work to propel the vehicle. The role … Read more
The major difference between a primary cell and the secondary cell is that primary cells are the ones that cannot be charged but secondary cells are the ones that are rechargeable. Before heading towards the discussion of differences between both … Read more
Thermodynamics is the branch of physics that studies the relationship between heat and other properties of a substance (such as pressure, density, temperature, and so on). Thermodynamics, in particular, focuses on how heat transfer is related to various energy changes … Read more
Calorimetry is the science of measuring the heat exchange between a system and its surroundings to calculate the change in energy of the system. The word Calorimetry is derived from the Latin calor (“heat”) and Greek metron (“measure”), and so … Read more
A calorimeter is a device that measures heat, which is required for calorimetry. Calorimetry is the branch of science concerned with measuring a body’s state in terms of thermal features to investigate its physical and chemical changes. What is Calorimeter? … Read more
