ways to find the molar mass of a substance. One way‚ if the substance is a gas‚ is to use the Ideal Gas Equation to find molar mass. The standard equation reads PV=nRT where “n” is the number of moles present‚ “P” is the pressure (which is obtained by reading the barometric pressure of the room with the class barometer)‚ “V” is the volume of the gas‚ “R” is the universal constant‚ and “T” is the temperature of the gas. The experiment’s objective is to calculate the experimental value of molar mass

spherical and elastic particles. Although an ideal gas is a theoretical model and so cannot exist in practice‚ most gases behave fairly similarly to an ideal gas. Gases behave more like an ideal gas when they are at a higher temperature and lower pressure‚ as the potential energy of the intermolecular forces becomes negligible compared to the kinetic energy of the gas. Butane gas does follow the ideal gas law fairly well‚ as it is non-polar and hence has

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

On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas

In the case of a cylindrical vessel of inside radius r and thickness t‚ we obtained the following expression for the hoop stress H and the longitudinal stress L. Mohr’s circle provides an alternative method‚ based on simple geometric considerations‚ for the analysis of the transformation of plane stress. Thin-walled pressure vessels provide an important application
