properties of dibromoethane such as critical temperature, pressure,
saturated liquid and vapor volume as well as using the general formulas
of the three gas laws. There are 7 graphs which plotted based on the
pressure and volume (PV) calculation and lastly a 3D graph showing
the relationshipsof temperature, pressure and volume. All these graphs
are plotted using the Matlab program.

Abstract
DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference are measured as a function of temperature. Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample.
Glass transitions may occur as the temperature of an amorphous solid is increased. Th
