Introduction

Aim: To see what temperature is the best for cleaning tea stained cloth. I am going to use a Safeway, biological washing powder. Prediction: My prediction is the hotter the temperature the cleaner the cloth gets, because the hotter it gets the more energy it has and it is able to move around more. Method: I will keep the test fair by using the same washing powder, the same amount of water, and timing it. I am going to put 50 ml of 40 c in a beaker with 3 mm of washing powder with one piece of tea stained cloth in each. ...read more.

Here is a diagram of the equipment: Results: Temperature Time cleanness 35 c 5 mins Dirtiest 4o c 5 mins Not very clean 45 c 5 mins A little cleaner then 40 c 50 c 5 mins Cleanest 55 c 5 mins 2nd cleanest I think my results are wrong because the normal temperature for biological washing powder is 40 c, but as you can see in the results table 40 c wasn't very clean. If my results are right then only two is wrong, which is 50 c and 55 c, because if it is the higher the temperature the cleaner it gets then 5o c and 55 c should be the other way around. ...read more.

Conclusion

I would put the tea stained cloth into a beaker with different temperatures and just leave them for ten minutes. To improve my experiment I would do a light test at the end to see how clean the cloth was. The light test would work by washing the cloth then putting a torch e.c.t. behind the it, the more the that comes through the cleaner it is. I would also go up 10 c instead of 5 c that way there should be more of a change in cleanness. I would also make it fair by doing the experiment all at the same time and on the same day. ...read more.
