JJ308 Engineering Laboratory 2EXPERIMENT : THERMODYNAMICS IDEAL GAS TITLE : COMPRESSION AND DEPRESSION AT CONSTANT VOLUMEDURATION : 2 HOURS

1.0 Experiment outcome

Thermodynamics is a basic engineering science course that introduces and applies fundamental concepts of thermodynamics. Thermodynamics is the study of work, heat, and energy, and the rules which govern how each of these is transformed into the others. The course explores relationship between properties of matter and basic laws of thermodynamics, which are fundamental laws of nature governing the behavior of all physical systems. Mathematical models of these physicals laws are presented and applied to systems involving pure compressible substances. These principles are used to analyze energy conversion process, cycles, devices and systems. Economic, environmental, sustainability and political implications are discussed to provide a context or the technical material. To investigate the compression and depression at constant volume.

2.0 Theory

The main distinguishing property of gases is their uncanny ability to be compressed into smaller and smaller spaces. Gases are also the least complex state of matter. The ideal gas law relates temperature, volume, and pressure, so that we can calculate any one of these quantities in terms of the other.Gases are easily expanded and compressible unlike solids and liquids. Gases have a measurements of pressure. Pressure is defined as force exerted per unit area of surface. It can be measurements in several units such as kilopascal (kPa), atmospheres (atm), and millimetres of Mercury (mmHg). Gas has a low density because its molecules are spread apart over a large volume. A gas will fill whatever container that is in.
