## Application of the first law of thermodynamics to various closed systems

First law of thermodynamics to Reversible Constant Volume Process In a constant volume process ( v = constant), the working substance is contained in a rigid vessel, So the boundary of the system is being rigid and no work interaction between system and surroundings other than paddle wheel work input. It will assume that “Constant … Read more

## Basic Concept of Specific Heats, Joule’s law and Enthalpy

What is specific Heat? The specific heat of a solid or liquid is defined as the amount of heat per unit mass required to a one-degree Celsius temperature rise. for small quantities, we have where m : mass of the substance c : Specific Heat dT : Change of temperature in degree Celcius Specific heats … Read more

## Zeroth Law of Thermodynamics & First Law of thermodynamics

What is the Zeroth Law of thermodynamics? Zeroth law of thermodynamics states that “if two systems are equal in temperature to a third system, they are all equal in temperature to each other”. According to Wikipedia: “The zeroth law of thermodynamics states that if two thermodynamic systems are each in thermal equilibrium with a third one, then they are in … Read more

## What is thermal Stress and Strain? Definition & Hoop stress

Thermal Stress & Thermal Strains The Stresses produced due to the change of the materials are known as thermal stresses or temperature stresses. If the temperature of the body is lowered its dimensions will decrease and if the temperature of the body is raised its dimensions will increase. The corresponding strains caused by thermal stresses … Read more

## Thermodynamics- Basic Concepts of Heat, Work & Energy

Energy Energy is a general term including stored energy and transition energy. The stored energy of a substance may be in the form of mechanical energy and internal energy. Part of the stored energy may take the form of either potential energy or kinetic energy. Rest of the part of the energy is the internal … Read more

## Basic concepts of thermodynamics

Definition of Thermodynamics Thermodynamics is an axiomatic science which deals with the relations among heat, work, and properties of systems which are equilibrium. It describes state and changes of state in physical systems. Macroscopic Vs Microscopic Viewpoint Thermodynamics studies are undertaken by two different approaches. Macroscopic approach: In the macroscopic approach, a certain quantity of … Read more

## Poisson’s Ratio & Relation between the Elastic Modulii

POISSON’S RATIO Let us assume If a body is subjected to a load ( Tensile), Due to this load the dimension of this body changes. its length increased while the area of the body decreased. The Ratio of this change in the length to the original length is known as Linear or Primary Strain and … Read more

## Stress and Strain in Bars in various conditions

Stress and Strain in a bar due to its self-weight A bar of length metre and area  A is fixed at one end. Let the density of material be ρ . Let us consider a very small shaded strip of bar ABCD of thickness at a distance y from the bottom end as shown in … Read more

## Fundamental of Stress & Strains

A force exerted on a body can cause a change in either the shape or the motion of the body. The unit of force is the newton, N. The three main types of mechanical force that can act on a body which change the shape of the body are as follows: Tensile Force Compressive Force … Read more
