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

Calorimetry Experiment Purpose: The objective of this lab is to determine the enthalpy change for NaOH(aq) + HCl(aq) NaCl (aq) + H2O(l) Procedure: Before measuring the enthalpy of acid base neutralization‚ my partner Brian and I determined a calorimeter constant‚ using a homemade polystyrene calorimeter. With the following formula and data: qhot= cm (Tf-Ti) qcold=cm(Tf-Ti) SYSTEM DATA SURROUNDINGS DATA Water cold Mass: 50mL Water hot Mass: 50mL C=4.18 C=4.18 Ti=20 C Ti=31

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

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

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

pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The
