ABSTRACT This experiment was carried out to determine the relationship between the pressure and the temperature of saturated steam in equilibrium. Besides that this experiment was also done to demonstrate the vapor pressure curve. The marcet Boiler was used for this experiment. When the pressure increases‚ the temperature also increases. Therefore‚ the relationship of pressure and temperature is directly proportional. The derived formulae and the data were used to calculate the slope. The dT/dP

observed that some of the mercury did not flow out and that the space above the mercury in the tube was a vacuum. After much observation‚ he concluded that the variation of the height of the mercury from day to day was caused by changes in atmospheric pressure. He never published his findings. His work in geometry aided in the eventual development of integral calculus.Torricelli’s chief invention was the mercury barometer‚ which arose from solving a practical problem.

digital gas permeameter). In addition‚ the gas flow expressed by the Darcy’s equation which relates volumetric flow and pressure drop with the properties of the fluid and media. The permeability is the production capacity of hydrocarbon reservoirs because it measure of how a reservoir fluid moves through the interconnected rock pores. It is usually measured at a confining pressure of about 300 to 400 psi on both horizontal and vertical core plugs. Permeability information play a role in determining

and allows this liquid to be heated in a water bath to a known temperature and escape from a flask through a tiny opening (Giunta‚ 2003). In this situation‚ vapours are assumed to be obeying the Ideal Gas Law‚ which is PV = nRT. P is the current atmospheric temperature‚ measured in atmospheres‚ V is the volume of the flask‚ n is the moles of the gas and T is the temperature of the water bath‚ measured in degrees Kelvin (Weisstein‚ 2007). R remains a constant‚ which is 0.08206 L atm/K mol (Weisstein
Premium Gas Pressure Evaporation
SUBLIMATION Sublimation is a technique used by chemists to purify compounds. Typically a solid is placed in a vessel which is then heated under vacuum. Under this reduced pressure the solid volatilizes and condenses as a purified compound on a cooled surface‚ leaving the non-volatile impurities behind. This cooled surface often takes the form of a "cold finger" (shown in the diagram above). Once heating ceases and the vacuum is released‚ the sublimed compound can be collected from the cooled surface
