EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

Title : The movement of substances across a semi permeable membrane Objective : To study the movement of substances across a semi permeable membrane Problem statement : What factor influences the diffusion of substances through a semi permeable membrane? Hypothesis : The diffusion of molecules across a semi permeable membrane is based on the size of the molecule Variables: a) Manipulated : Size of solute molecules b) Responding : Colour of solution c) Fixed : Temperature and time

It would have been inconceivable at the turn of the 20th century to imagine the musical freedom‚ variety‚ and subcultures that we have today. What began as a counterculture movement in the 1950s and 1960s eventually gave rise to an incredible array of different types of music‚ rock being the most prevalent and ubiquitous among them. Other music scenes followed; punk rock‚ grunge‚ disco‚ R&B‚ and psychedelic rock to name just a few. A great question is how all of this came about – how did a very

Experiment D-Pre-lab: Synthesis of a Room Temperature Ionic Liquid (RTIL) Name: Morgan Smith Student #:130635880 Date Submitted: November 7‚ 2014 Lab Section: Friday 2:30pm‚ Section 9 T.A: Matt Halloran 1. Refer to the last page. 2. Arrow pushing mechanism: 3. Refluxing is when the reactants are boiled and the vapor that is produced is cooled. When the vapor is cooled it changes back to its liquid state and returns to the flask. 4. The visual cue that allows you to determine that the

KF 1(a) SOLUBILITY OF AN SALT BY TITRATION Date : __________________________ Name : _____________________________________________________ Matric no. : __________________________ 1. Objective(s) of Experiment To measure the change in solubility product of potassium periodate (KIO4)‚ when an inert salt (NaNO3) is added to the solution. 2. Why important to determine solubility? The solubility product expression can be used for predicting whether or not precipitation will occur

How do we breathe? Clara and Dominic have both produced a statement‚ upon how the bell jar represents the way we breathe‚ our respiratory system. Clara states that the model is correct as it shows that we breathe because the diaphragm moves up and down‚ on the contrary Dominic says the model is incorrect as we breathe with our ribs. My conclusion on who is correct is that Clara is correct because the diaphragm does move up and down when we breathe‚ however‚ Dominic‚ in a sense‚ is also correct

Stanford king size permanent marker‚ Marks a lot and Redi Mark +. Ingredients in the permanent marker ink: Permanent inks contain three main ingredients: colorant‚ carrier (solvent)‚ and resin (polymer). Pigments do not fade like dyes and do not bleed through paper. Solvents for the old markers (up until the 1990 ’s) were nasty-smelling organic chemicals such as xylene. Nowadays‚ the solvent of choice is an alcohol (ethanol or isopropanol)‚ which is more environmentally friendly and better smelling

Breaching Experiment In the eye contact experiment I decided to do this in a room with about six of my friends while watching the All Star game‚ I used my Girlfriend. I waited until everyone was focused on the game and then begin to stare at her from across the room‚ at first her reaction was to wave at me and smile then she started to look around to see if I was starring at someone else‚ then she told her best friend "I don’t know what’s his problem‚ he is being too weird." I extended my eye contact

Olentangy River Road. To gauge whether or not traffic control is necessary‚ vehicles are timed at a specific interval to give a range of varying speeds; these speeds could then be compared to the set speed limit on the road. The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding. The sections that follow describe the process‚ calculations and answers to this experiment. Section 2 will describe the tools and step-by-step processes
