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

Aim The aim of this investigation is to identify the inglorious immobile. possibleness: I predict that if we female genitals identify the noncitizen being solid, by finding its melt tear down shoot downwardly in a body of water bath, and match it with the periodic table. varying: Amount of the unknown substance Heat given to the water bath Output: Temperature of the unknown substance Method: Equipment: * bunsen burner * Tripod * Unknown solid * Beaker * Stopwatch * simmering thermionic tube * Stand * Clamp * Thermometer First we dispense some meter to set up the equipment, and afterward checking that eachthing is safe, we start boiling the beaker make full with water, having a boiling tube with the unknown substance deep down it. Since this is group work, and to occupy it fair, we take turns recording the temperature every 30 seconds or looking at the stopwatch. By changing our shifts every 5 minutes, this will make us to have a fair chance of working. We than sour of the fire once the solid melted.

I think we have been doing come up on it, without doing anything things wrong. Also we should have turned the fire down a little bit, for the temperature suddenly rised from 80 to 86 degrees. Modifications to received Plan: I got an idea of doing it in turns during the frame-up for the investigation. Since surface-to-air missile agrees in my...
