Energy revisited …

From the molecular view right now there exist three general watch, forms of energy:

Intermolecular Potential energy: It is associated with the makes between the molecules. Molecular Kinetic energy: It really is associated with the translational velocity of individual elements. Intramolecular strength: It is associated with molecular and atomic structure and related force a couple of

Low Density Gas

• A In very t low deb densities, the ii h average ranges between elements are very d l l large and d intermolecular potential strength can n neglected. always be l g • In such instances, particles happen to be independent of every other - this is termed as an Ideal Gas.

Ideal Gas Equation of State

• The simplest and best known equation of condition for substances in the gas phase is the Ideal gas Equation of Express.

Ideal Gas Equation of State PV = mRT Pv = RT

• The gas that obeys this regards is g y named an Ideal Gas. • Exactly where R (Gas constant) is unique constant for every particular gas gas. • The value for R for several substance is given in Stand A 5 A. five

Ideal Gas Equation of State

• Because of getting simple straightforward, ideal gas equation is used in thermodynamic calculations, whenever we can. • It really is applicable to actual gas at low density. • At low pressure and high temperature, the density of gas g d it f decreases and gas b l d reacts as an excellent gas below these conditions

Non-Ideal or Real Gas

•Low Temperature •High L Hi they would Pressure •Particle size significant compared to space between debris ti t Interactions •Interactions between allergens are significant

Ideal Gas Equation of State

• At low pressure and high temperature the temperature, density of gas decreases and gas behaves as an ideal gas beneath these conditions conditions. • Over what range of denseness Ideal Gas Equation of Sate carry with accuracy and reliability? • Just how...
