ABSTRACT The densities (ρ) and viscosity (η) were reported for binary mixtures of N-methylformamide with O-substituted aniline (2-chloroaniline‚ 2-methylaniline and 2-methoxyaniline) over the entire composition range from 303.15 K to 318.15 K and at atmospheric pressure 0.1 MPa. These experimental data have been used to calculate excess volume (VE)‚ deviation in viscosity (∆η) and excess Gibbs energy of activation of viscous flow (G*E). The variations in these properties with composition for all the binary

conditions‚ pressure exerted on the surface of a liquid is the atmospheric pressure. If this atmospheric pressure is reduced on the surface of a liquid‚ by some means‚ then the liquid will start boiling at lower temperature‚ because of reduced pressure. This basic principal of boiling of liquid at lower temperature by reducing the pressure on its surface is used in steam jet refrigeration system. The boiling point of pure water at standard atmospheric pressure of 760 mm of Hg is 1 00°C. It may be noted that

Becca DeHaven ChemC-125 Avogadro’s Law Experiment Report Introduction: The following experiment’s purpose was to confirm Avogadro’s Law and experimentally determine the Universal Gas Constant “R”. Amedeo Avogadro hypothesized that all gases of equal volume‚ temperature and pressure would contain equal amounts of moles. This idea that volume is directly proportional to moles sprung from other similar hypotheses. Robert Boyle found that pressure and volume are inversely proportional‚ meaning as pressure

Experiment 1 The Heat Capacity Ratio of Gases Purpose The purpose of this experiment is to calculate the heat capacity ratio of gases‚ Helium‚ Nitrogen and Carbon Dioxide‚ and compare with their theoretical values. Introduction Thermodynamics is the study of heat as it relates to energy and work. There are various properties which all relate to each other when determining the characteristic of a certain substance. One of such properties is heat capacity‚ which is the amount of heat energy

Abstract The aim of this experiment is to determine the heat of combustion for naphthalene. This is the some basic bomb procedures. In this experiment‚ we us naphthalene as a fuel in bomb calorimeter which naphthalene powder is turned to pellet using pellet press. The fuel is burnt at constant volume condition in a high pressure container (the bomb). The whole bomb‚ pressurized with excess of oxygen. The mass of iron wire‚ ma =0.02g. The mass of naphthalene pellet with iron wire‚ mb =0.38g. The

Pressure tendency can forecast short term changes in the weather.mercury barometer has a glass tube with a height of at least 84 cm‚ closed at one end‚ with an open mercury-filled reservoir at the base. The weight of the mercury creates a vacuum in the top of the tube. Mercury in the tube adjusts until the weight of the mercury column balances the atmospheric force exerted on the reservoir. High atmospheric pressure places more force on the
