    Jacques Charles invented a couple of different things. Some of these are the valve line‚ the appendix‚ the nacelle‚ and the hydrometer. The valve line is a device that releases gas from a balloon and would ensure an easy descent. The appendix is a tube that lets expanded gas out of the balloon. The appendix will prevent the balloon from bursting from its internal pressure. The nacelle is a wicker basket that is held onto a hot air balloon by ropes. And finally a hydrometer

    escape‚ the methanol/unknown vapour pushed out the extra vapour and oxygen gas. When the flask was cooled down‚ the methanol/unknown vapour condensed – this resulted in the increase in mass of the flask when it was weighed after being cooled down. The mass of the condensed vapour is equal to the difference between the initial and final masses of the flask. Due to the assumption that the volatile liquids obey the Ideal Gas Law: PV=nRT‚ where n is equal to the mass of the substance divided by the molar

    Formulas: Write the following formulas. Ideal Gas Law Molar Mass Relationships: The Dumas Method - In 1826 Jean-Baptist Dumas developed a method for determining the molar mass of liquids that can be boiled under laboratory conditions. At that time the concept of the mole was not yet understood so Dumas studied the relative densities of the vapors by using Boyle’s‚ Charles’ and Avogadro’s Laws. In this experiment the ideal gas law will be utilized to solve for the number of

    The Camesia gas pipeline‚ which runs from the amazon‚ over the Andes‚ to the pacific coast has been raising a lot controversy in the past decade with its destruction of the Peru rainforest. It has ruptured 4 times with at least three major spills in the first 18 months since it was constructed in 2004. With 22 indigenous communities living in a state reserve in isolation‚ a contractor by way of helicopter has made contact with these isolated communities and is pressuring them to abandon their ancestral

    Both the graph and the table represent the same thing‚ the temperature of the solution during fractional distillation. At the start of the fractional distillation‚ before we started the fire‚ it was 25° celcius. At the end of the fractional distillation‚ when all of the liquid was gone‚ it was 99.3 degrees. This set of data is not the first time we did the fractional distillation‚ it’s actually probably the 3rd or 4th. The first time we didn’t actually record the temperature‚ we just looked for the

    to maintain a constant pH and temperature. Sparger • The sparger is an apparatus used to introduce gasses into the vessel. • Spargers are located at the bottom of the vessel and consist of a tube with tiny holes for the gas to escape through into the culture. • The gas coming out of the sparger helps to aerate and mix the contents in the vessel‚ as well as supply oxygen to the cells. Baffles • Baffles are obstructions on the side of the vessel that generate turbulence in the flow of the culture
