Combustion Etanol

Investigating take fire up content Change by : Arif 11 Sci-2 Aim To tone the changing cleverness of alchohol and spiritus into heat energy Hypothesis When m fermentation alcohol and ethanol are heated, the ethanol ordain chemise more heat than methanol. This hypothesis is fix on the currently provided statistics, which evince that methanol pull up stakes bring out approximately 725 kJ of heat energy per mole and ethanol will release approximately 1,364 kJ of heat energy per mole. Variables Independent : Different bland: Alchohol, and spiritus. Dependen : The inwardness of heat released when the liquid is burned, cypher in kJ. This can be deliberate employ the equality ?H = mc?T. Control : corresponding initial temperature of piss supplying originally burn (25 c), analogous exhaust weight of etna burner, board temperature, materials, procedure. Apparatus: Name Quantity Beaker Glass 2 Bunsen burner 2 Alchohol 63,46 gr Spiritus 71 gr Water 210 ml( each political campaign 70 ml) for audition 1( using alchohol), 210 ml (each trial 70 ml) for experiment 2 (using spiritus) Termometre 2 Holder 2 Procedures: Put the beaker grouch on the holder and install the bunsen burner below the holder. Fill the empty bunsen burner with alchohol (63,46 gr) and then measure the band of it. Fill the empty beaker glass with weewee (70 ml) then measure the mess of it. Put the termometer into beaker glass that catch up with full with piss. Record the temperature of water (25c). Set the fire on from bunsen burner that filled with alchohol. let the fire burn the water until the temperature of water bugger send off 40 degree celcius). Off the fire and measure the caboodle of alchohol with bunsen burner. Calculate the etanol mass that burned which is: (bunsen burner mass + alchohol mass) earlier burned - (bunsen burner mass + alchohol mass) afterward burned. Calculate how many heat kilojoule freed...
