Paraffin wax. Categories: physics experiments, thermodynamics and heats.. In this experiment, we Determine the melting point of wax from its cooling curve .
Properties. Paraffin wax is mostly found as a white, odorless, tasteless, waxy solid, with a typical melting point between about 46 and 68 Â°C (115 and 154 Â°F), and a density of around 900 kg/m3. It is insoluble in water, but soluble in ether, benzene, and certain esters.
Petroleum Engineering Lab. Experimental Data Sheet. Experiment Title: Melting Point Experiment. Objective: To determine the melting point of pure paraffin wax.
Experiment-1. Requirements â€“ Given Solid Substance, Capillary Tube, Paraffin, Laboratory. Every pure solid has a characteristics melting point therefore.
You shall practise your technique with cold copper coins and boiling water. You shall then repeat the method with stearic acid and paraffin wax.. for the cooling curve experiments, it was hard to note down the exact temperature reading whilst
1 Sodium chloride behaves as an insulator until it is nearly at its melting point, and then it readily conducts.. 2 Paraffin–wax remains an insulator even when it has melted. It is made up of long-chain molecules consisting of carbon and hydrogen atoms.
The melting point of candlewax is the temperature at which: 1. The solid material turns to liquid (by heating it up). 2. The liquid turns to solid (by cooling it down).
