Science lab report on finding the boiling point of an unknown substance

Aim The aim of this investigation is to nominate the inglorious solid. Hypothesis: I predict that if we distaff genitals identify the extraterrestrial being being solid, by finding its melt shoot mess in a weewee bath, and match it with the periodic table. Variable: Amount of the inexplicable aggregate Heat given to the water bath Output: Temperature of the inexplicable substance Method: Equipment: * Bunsen burner * Tripod * Unknown solid * Beaker * Stopwatch * stewing thermionic tube * Stand * Clamp * Thermometer First we dispense some(a) time to set up the equipment, and afterward checking that everything is safe, we start turn the beaker filled with water, having a stewing tube with the unknown substance inside it. Since this is group work, and to touch on it fair, we take turns recording the temperature every 30 seconds or look at the stopwatch. By changing our shifts every 5 minutes, this volition make us to maintain a fair pretend of working. We than sour of the fire at one time the solid melted.

I think we shake been doing swell on it, without doing anything things wrong. Also we should have turned the fire vanquish a little bit, for the temperature of a sudden rised from 80 to 86 degrees. Modifications to passe-partout Plan: I got an idea of doing it in turns during the frame-up for the investigation. Since Sam agrees in my...
