Poisson’s ratio is the negative of the ratio of transverse strain to lateral or axial strain in physics. It is named for Siméon Poisson and is represented by the Greek letter ‘nu.’ For values of these changes, it is the ratio of transversal expansion to the amount of axial compression. The Poisson effect occurs when […]

Iso stands for constant and thermal stands for temperature. Isothermal processes are the processes in which the temperature is constant. Compression is the process in which the volume of the system is decreased or the pressure is increased. Isothermal compression is the process of compression in which the temperature is constant. It is a thermodynamic

Inverse variation is a type of proportionality that on increasing one quantity, the other quantity decreases and vice versa. Moreover, if we dig deep into the concept of indirect variation, we will get to know that the product of two variables in the variation equation will always produce a constant.  For example: When we say

Any thermometric scale having a reading of zero that corresponds to the theoretical absolute zero of temperature—that is, the thermodynamic equilibrium condition of minimal energy. The Kelvin (K) scale is the standard measure of temperature in the International System of Units. It is an absolute scale defined by the Boltzmann constant, which is 1.380649 x

The quantity of water vapour in the air is referred to as humidity. Water vapour is the gaseous condition of water that is imperceptible to the naked eye. Humidity may be expressed in a variety of ways, including absolute humidity, relative humidity, mixing ratio, and moisture content. As the temperature rises, the levels of water

As well as being known by the abbreviation “Hess’ law,” Hess’ law of constant heat summation is an important relationship in physical chemistry that was named after Germain Hess, a Swiss-born Russian chemist and physician who published it in 1840. In accordance with this concept, the total enthalpy change that occurs during the whole course

Pressure is essentially characterised as the measure of force per unit area. When attempting to comprehend pressure, the central issue is to ponder what occurs on the nuclear level in a fluid or gas at high tension. The constituent atoms are continually moving near, which implies they’re catching the dividers of the holder constantly. The

The change in length along one dimension over volume is referred to as linear expansion. A rise in the temperature of a substance causes this phenomenon. In this post, we’ll look at the coefficient of linear expansion, how it works, and how it might be used. Coefficient of Linear Expansion The term “expansion” can be

Introduction Everything we observe around us has a binding force and energy that binds it together. The nucleus, too, consists of protons and electrons, which are strongly bound by energy.  Binding energy can be defined as the least amount of energy needed to remove a neutron, proton, or electron from the nucleus. For example, a

Introduction Avogadro’s number, named after Amedeo Avogadro, equals approximately 6.022 x 1023. Avogadro’s number tells us how many molecules are in 1 gram-molecule of a substance. Avogadro’s number depends on the substance and its temperature; it is a universal constant. The number is the same regardless of what type of molecules are in the substance.
