Yesterday in period 2 we boiled water using Bunsen burners. We first had to get our gear and set the Bunsen burner up, after we got the beaker and put water in halfway and checked the temperature, then we light up our Bunsen burner, we left the water there for 5 minutes after we checked the temperature again, we did this for 2 different flames the safety flame and the roaring flame. The safety flame is the least hottest flame, the roaring flame is the hottest flame. What was hard nothing was hard, what was easy lighting the Bunsen burner. My favourite part was when one of the groups melted the plastic at the end of the thermometer. The aim was to see which flame on the Bunsen burner heats the water. Conclusion: The hottest flame is the roaring flame because the more you open the air hole the hotter the flame will get, the flame gets hotter when the air mix's with the gas.
Well done Riansha you carried the experiment out well and got good results that clearly show the blue flame is the hottest.
ReplyDeleteWas it a fair test?
To insure that your experiment is a fair test, you must change only one factor at a time while keeping all other conditions the same. What factor did you change and what factors did you keep the same?
(I think the group who broke the end of the thermometer accidently dropped it!!)
