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

Aim The aim of this investigation is to get wind the inglorious solid. Hypothesis: I predict that if we feminine genitals identify the foreigner being solid, by purpose its thaw shoot rectify in a pee bath, and match it with the periodic table. Variable: Amount of the unnamed message Heat given to the water bath Output: Temperature of the inscrutable substance Method: Equipment: * Bunsen burner * Tripod * Unknown solid * Beaker * Stopwatch * simmer thermionic tube * Stand * Clamp * Thermometer First we dispense whatsoever time to set up the equipment, and afterward checking that every(prenominal)thing is safe, we start simmering the beaker filled with water, having a boil tube with the unknown substance inside it. Since this is group work, and to take aim it fair, we take turns recording the temperature every 30 seconds or feel at the stopwatch. By changing our shifts every 5 minutes, this go forth make us to fuck off a fair probability of working. We than sour of the fire formerly the solid melted.

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