the density of the solution increases. From this‚ it can be concluded that as the solution density increases‚ the angle of refraction also increase. There were two possible outliers at the 5% and 10% concentration‚ they could be possible random errors that occurred within this experiment. However‚ looking at figure 6‚ the outliers could have occurred only due to the scale setting in graphs. Also the overall trend demonstrated in figure 4 was an exponential increase‚ however that may be due to the way

In this experiment I will investigate the temperature of 50cm³ of water before and after I have added calcium chloride‚ I will gradually increase the amount of calcium chloride by 1 gram to see if there is a significant change. When Calcium Chloride is mixed with water it performs an exothermic reaction which makes new bonds between the salt (Calcium Chloride) and the water. This will therefore make the solution of the reaction increase in temperature. Exothermic reactions transfer energy

Applying Archetypal Analysis in Marketing Research © Paul Riedesel‚ Action Marketing Research 2008 Archetypal analysis is a mathematical procedure for decomposing a multivariate dataset as a function of a set of underlying archetypes or ideal types. While used for many years in the physical sciences‚ these methods were first introduced to marketing research practitioners by Louviere and Carson at the 1998 Advanced Research Techniques Forum. Little public use has been made in our field since then

A second Pew study‚ the following year‚ added another disturbing dimension to the picture‚ revealing that one in 31 adults in the United

Data Analysis The investigation I did was to find the resistance of a piece if wire. The piece of wire is my dependent variable throughout the investigation. I changed the length of the wire in order to measure the resistance of each length. Plan In this investigation‚ a simple circuit will be set up to read the voltage and current when the length of the wire changes. The length will range from 10cm-80cm with intervals of 10cm. The length of the wire will be changed by moving the crocodile clip

Interpretation of Data When looking at my results i can safely say that the change in HCl concentration does affect the rate of reaction with the Calcium carbonate pebbles. The relationship between the change in HCl and reaction rate can be seen in the graph and raw data table presented above. If you compare the lowest concentration with the highest concentration you’d be able to see that there is a very large contrast between their averages. The average gas production of 0.1M HCl was 0.00693 kPa/s

Discussion The results did not give enough accurate data‚ due to the ability of the catapult and the weights used‚ the point at which the projectile stopped being efficient was not evident. If the experiment had been undertaken in more controlled and technology used more efficiently‚ like a robotic catapult‚ than the effect of weight on the motion of a projectile would have become more apparent. Furthermore‚ the reliability of the experiment would be drastically increased due to the use of more
