tablets. In the experiment they first tested how long an Alka-Seltzer tablet would dissolve in cold water ( 9 degrees) then repeated it two more times in order to calculate a mean. Then using a hot plate to heat the water‚ they tested another tablet in the hot water (51 degrees) to see how long it would take to dissolve and again did it two more times to calculate a mean. Finally they tested another tablet in water left on the hot plate for thirty-seconds (81 degrees)‚ preformed the experiment for two more

Conclusions At the end of Part A in this experiment‚ it can be determined that Sodium Chloride had the highest amount of conductivity tested by all groups. On the graph above‚ the data shows that NaCl (sodium chloride) held the highest amount of electrical conductivity for all groups and on the table it reads the highest numbers across its row. Also as seen in the data above‚ ethanol had the lowest amount of conductivity with sucrose‚ acetic acid‚ ammonia‚ and MgCl2 following in ascending order

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

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

In food it is common to use Nisin at levels depending on the food type regulatory approval. Nisin cannot be produced chemically therefore it has to be synthesised using fermentation. During fermentation various stages of growth occur and as a result different conditions can occur during this fermentation process‚ eg pH‚ most organisms produce acid as they grow and therefore in the Lag phase ( a period of adptation for the cells to their new environment‚ new enzymes are synthesized) and in

the antibiotic penicillin‚ as well as in industry and food preparation. For a long time fungi were classified as plants‚ mainly because of their similar lifestyles - both are seen to grow in soil and are sessile (permanently attached; not moving). Plant and fungal cells both have a cell wall‚ while cells from the animal kingdom don’t. Fungi are thought to have diverged from the plant and animal kingdoms about one billion years ago. Human feet have hundreds of fungi - researchers from the National Human Genome
