In this lab, two methods of distillation (simple and fractional) were utilized to separate a mixture of volatile compounds (cyclohexane and toluene). As a first observation of the results and data generated, looking specifically at the simple and fractional distillation curves, it seemed that the fractional curve obtained was not as expected. In fact, it was not very different from the simple distillation curve, having a gradual positive slope. This means that there was actually not a big…

The objective goal of this experiment is to identify a set of unknown liquids by measuring the liquids of three physical properties which consists of determining the density, solubility and boiling point of the liquids A, B, C and D. Ethyl acetate, methanol cyclohexane and acetone were the unlabeled liquids. In the data analysis the predictions came out to be liquid A for acetone, liquid B is for ethyl acetate, liquid C is methanol and liquid D is cyclohexane. Introduction and Experimental…

Maciej Szwoch Chm 131-005 5/5/18 Writing Assignment Figure 1 [This diagram shows at what temperatures/pressures water changes phases. As shown in Figure 1 (“Interactive Student Tutorial”) above water turns into a gas at 100 degrees Celsius. At 0 degrees Celsius and below it becomes a solid. This diagram makes it easy to see that the energy needed (temperature) to change phases greatly increases] Molality Molality is the number of Moles of solute divided by kilograms of solvent (Tutapoint…

technology. Of the two main fossils fuels used, natural gas offers the best economics and efficiencies and is the main pathway used to generate hydrogen nowadays, mainly for the production of ammonia and methanol. The other, being coal, can also be used to produce hydrogen but the initial investment is much greater and the efficiency is lower compared to when natural gas is used. Coal can be economically favourable when compared with natural gas for its lower feedstock cost [$1.26 per GJ LHV…

plasmas) move faster, they carry more kinetic energy and feel warmer than a material with slower particles. Boiling Boiling is the process where molecules transition from the liquid phase to the gas phase, resulting in the formation of vapour bubbles within the liquid (Figure 1). Figure 1 – Liquid changing to a gas. Boiling Point Boiling point is the temperature at which the vapour pressure of the liquid equals the environmental pressure that surrounds the liquid. At boiling point, the vapour…

Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…

The results from the experiment generally show the trials with full light intensity to have produced more oxygen, showing the elodea samples to have photosynthesised more than the lower light intensity trials. Trials 1 and 2 were in water bath 1 with full light intensity, whereas Trials 3 and 4 were in water bath 2, with lower light intensity. Experimental error caused the trials with the lower light intensity to be disrupted, and no data was collected for these trials on Day 8 of the experiment…

pressure across the film. Hence the permeability coefficient (P) is the proportionality constant between the flow of the penetrant gas per unit film area per unit time and the driving force (partial pressure difference) per unit film thickness. The amount of gas penetrating through the film is expressed in terms of either moles per unit time (flux) or weight or volume of the gas at STP. Commonly, it is expressed in terms of volume. The permeability coefficient (P), as defined by Eq. 2.24, is…

4.2 Glass Blowing Glass blowing is a glass-forming process that encompasses inflating molten glass into a bubble, with the help of a blowpipe. A person who blows glass is called a glassblower or gaffer. A person who manipulates the glass with a torch or other tools is known as a lampworker. 4.2.1 Principle of Glass blowing Glassblowing utilizes a working property of glass known as inflation. This refers to the expansion of glass by passing a small amount of air into it. The property exists…

The Mpemba Effect The Mpemba effect is a rather unusual physical phenomenon where hot water freezes faster than cold water, under certain conditions. Intuitively, this doesn’t make any sense. How could water of higher temperature reach freezing temperature quicker than water of colder temperature? Water freezes when it’s molecules lose energy and slow down enough to stick together, forming ice. The molecules of water of high temperature have more energy the molecules in the colder water. So,…
