Does the Colour of a Liquid Effect How Fast it Cools? :: essays research papers

Does the Colour of a Liquid performance How Fast it Cools?I am trying to find out if the color of a suave effects how quickly it cools down.Method1.First I took five test tubes and filled to each one one with 5ml of black, blue, green, red and discharge colouring (for the clear colouring I simply used water.)2.I then filled each of the test tubes with 25ml of boiling (of course whilst wearying safety goggles.) water and waited for the temperature to fall to 50C and then measured the temperature of the water, using thermometers, every 30 seconds for three minutes.3.I recorded our results and perennial the experiment to make the test fairer.Diagram My diagram can be found in the plastic wallet this was pass in with.Equipment5 standard test tubes.5 thermometers.Four colour dyes, black, blue, green and red.A stop watch.A kettle.PredictionI think that the colour of the liquid will effect how quickly it cools down because I know that night matt surfaces are better at absorbing ra diation. Therefore, according to my theory, the darker dyes much(prenominal) as the black, blue and green will cool slower than the hoy ones.ResultsThese are my average results for both sets of recordings put into tablesGreen condemnation temp (C)000500304910048130472004723046RedTimeTemp (C)000500304510043130422004123040BlueTimeTemp (C)000500304710044130422004123040 causticTimeTemp (C)000500304710044130422004123039 egestTimeTemp (C)000500304810047130452004423037I then put these results into a graph which you can find in the plastic wallet this was handed in with.I then worked out the total temperature loss for each colour and put them into this tableRedGreenBlueBlackClearTotal Temperature Loss in C104101113I then put the results into this stripe chartConclusionMy results seem very strange and almost conflict my prediction. All the results seem quite similar, except the green dye, which, of course, could simply be an anomalous result. Therefore my conclusion is that the colour of a liquid makes no difference to how quickly it cools down.EvaluationI understand that my experiment was non at all completely accurate. To be so I would desire to do it in a controlled, stable environment, but this was not usable to me.
