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

Does the Colour of a Liquid Effect How Fast it Cools?I am trying to find away if the colour of a liquid effects how quickly it stills slew.Method1.First I took five test tubes and filled each one with 5ml of black, blue, green, red and rack up headway 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 wearing preventive goggles.) water and waited for the temperature to f any to 50C and then measured the temperature of the water, using thermometers, every 30 seconds for three minutes.3.I recorded our results and repeated the experiment to make the test fairer.Diagram My diagram can be found in the tractile wallet this was handed 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 dark matt surfaces are better at absorbing r adiation. Therefore, according to my theory, the darker dyes such as the black, blue and green will cool slower than the lighter ones.ResultsThese are my average results for both sets of recordings put into tablesGreenTime temporary (C)000500304910048130472004723046RedTimeTemp (C)000500304510043130422004123040 regretfulTimeTemp (C)000500304710044130422004123040BlackTimeTemp (C)000500304710044130422004123039ClearTimeTemp (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 kick downstairs chartConclusionMy results seem very strange and almost contradict my prediction. All the results seem quite similar, except the green dye, which, of course, could simply be an chimerical result. Therefore my conclusion is that the colour o f a liquid makes no difference to how quickly it cools down.EvaluationI understand that my experiment was not at all completely accurate. To be so I would need to do it in a controlled, stable environment, but this was not available to me.
