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

Experiment in Physics Lab Report Renelle L. Gapay Department of Physics Isabela State University-Ilagan Campus‚ Calamagui 2nd‚ City of Ilgan‚ Isabela Ellenergapay_23@yahoo.com Abstract In this experiment you can prove that electric charges can produce by using only a balloon and pieces of papers you can understand further static electricity and charges. And how it is produced. Introduction Have you ever wondered why rubbing a balloon make pieces of paper attract with it? The effect

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

After the TLC was placed inside a UV chromatography box‚ it appears that the sample analgesic contains D‚ which is mefenamic acid. Keywords: Chromatography‚ Pigments‚ Analgesics‚ TLC Results and discussion Thin layer chromatography is a useful method of quickly determining the main active ingredients of commercial analgesics containing aspirin (A)‚ acetaminophen (B)‚ caffeine (C) and mefenamic acid (D). Thin‑layer chromatography involves the same principles as column chromatography‚ it also is

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

Measuring the Enthalpy change of combustion Abstract This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels‚ hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel‚ amount of fuel used and the enthalpy change of combustion. Introduction Enthalpy change of combustion is the enthalpy change when

advantages and disadvantages of using ethnographic methods for sociological research I am going to look at the advantages and disadvantages of using ethnographic methods for sociological research. Ethnography is in-depth research into people’s lives through the use of primary data such as Observations and Interviews‚ and also secondary data such as diaries‚ and official documents. The first method of research I am going to look at is a primary research method that is unstructured interviews. There are

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
