pressure decreases the volume increases. But the volume only increases very little even though the pressure has dropped significantly. 2) Do you think there is a point at which volume cannot be decreased any further for this sealed container of gas? Explain your answer in terms of what you know about the properties and characteristics of gases. [5 points] I think that the higher the pressure gets‚ the less volume there is.

METHODS 2.1. Nature of Reactants 2.1.1 We placed 3mL of 3 M HCl into each of 3 seperate test tubes. Next we added mossy zinc to the first test tubes‚ Sn granules to the second and Cu filings to the third and compared the rates of evolution of hydrogen gas in each test tube. 2.1.2. We mixed 3mL of 0.02 M KMnO4 and 2mL of 3 M H2SO4 in a test tube and stirred using a glass rod. Next‚ we divided the solution into two. We added 2mL of 0.03 M Na2C2O4 solution to the first half and 2 ml of H2O2 to the second

Orsat Gas Analysis Experiment I. Objectives To analyze the dry exhaust gas (DEG) from a combustion system using the Orsat apparatus. II. Apparatus As shown in figure‚ the Orsat apparatus consists of a water-jacketed 100-m1 burette B connected at its top to a glass manifold M and at its bottom to a leveling bottle L. The glass manifold M is connected to three reagent bulbs called pipettes P1‚ P2 and P3 via three cocks C1‚ C2 and C3. Each tube is filed with its own absorbing chemical solution:

Ejectors Give Any Suction Pressure Recent tests on multistage ejector systems will simplify your task of designing vacuum-producing equipment for any pressure. F. DUNCAN BERKELEY GRAHAM MANUFACTURING CO.‚ INC.‚ BATAVIA‚ N.Y. B ecause of overlapping performance‚ it’s often a lengthy problem to arrive at the most economical design of an ejector. In practically every new application of high vacuum‚ we find it necessary to investigate thoroughly the many available means of producing vacuum

BHOPAL GAS TRAGEDY By URJIT ZAVERI 14BLS119 On the night of December 2‚ 1984 forty one metric tons of methyl isocyanate also known as MIC was released from the Union Carbide factory in Bhopal. After one year of this incident almost 1800 people dies in this disaster and 320‚000 people had been affected by it. By 1991‚around 4000 people dies because of the gas in their body. Union carbide was a U.S company that started manufacturing pesticides in Bhopal‚ India. The valve malfunctioned on the 2nd December

TITLE Vapour Liquid Equilibrium OBJECTIVE To find the Vapour-Liquid Equilibrium (VLE) relationship for binary mixture and to plot the equilibrium curve. INTRODUCTION The term equilibrium is referred to as when a system is in a static condition and there is absolutely no changes that occur as time goes by. Vapour-liquid equilibrium is a condition where a liquid and its vapor are in equilibrium with each other‚ a condition or state where the rate of evaporation is equal to the rate of condensation
