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

amazing thinkers was Galileo Galilei. Galileo was an extraordinary astronomer and inventor. Galileo was born on February 16‚ 1564‚ the oldest of six children in his family. His father‚ Vincenzio Galeli‚ was a merchant and also a musician while his mother‚ Giulia was just a housewife like most wives during their time. It is very interesting that Galileo was so interested in science while his father was a composer and musician. His father was an accomplished lutenist and made sure Galileo knew how to play

the yellow water is not allowed to mix with the green. Analysis questions/answers 1. Q-Based on your observations in the lab‚ what do you think happens to the majority of water (not ice) at the poles? A-The majority of the water freezes because water is the only molecule that doesn’t sink‚ so the water becomes ice. 2. Q-Based on your observations in the lab‚ what do you think happens to most of the water at the equator? A-The majority of water at the equator

The Manland Experiment 1. The Manland experiment lasted only one weekend in one store. The marketing advantages and disadvantages of expanding it to other stores? Do you think IKEA should do more with this idea? Why or why not? The advantage was this was an attempt to continue IKEA’s image as family-friendly with the goal to appeal to all men as an environment offering a rewarding shopping experience. The area was set up for men to play video games or watch sports while their wives or girlfriends

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)

Individual Project Unit 2 Experiments In this individual project we were asked to conduct three experiments. The three experiments I chose to conduct were Experiment 1‚ Experiment 2‚ and Experiment 4. I have documented my findings for the experiments that were done. In Experiment 1‚ I was to rub my index finger gently over a piece of very coarse sandpaper for a few times. Then‚ I was to rate its coarseness on a scale from 1 (very soft) to 7 (very coarse)
