Combusion Of Candle Wax

Heat Of Combustion Of compact disk Wax Purpose:The designing of this investigate was to determine the amount of heat that was released when a chiliad of see wax burns. Materials and Equipment: Empty out give the bounce Candle attached to a snatch of cardboard Celsius thermometer Ring fend for Iron ring Stirring rod 250mL beaker 100mL graduated cylinder Ice information and Observations: concourse of pop can and piss:149.88 grams Mass of go off pop can: -14.05 grams Mass of water in pop can:135.83 grams Mass of a see stuck to a piece of cardboard: 31.77 grams Mass of cd and cardboard after candle burn: -31.01 grams Mass of candle burned: 0.76 grams Final temperature of water in pop can: 35.0 (C Initial temperature of water in pop can: -9.5 (C neuter in temperature: 25.5 (C Calculations: q = m ( c ( (T q(# of cal. or joules absorbed by the water) = m(mass of water in grams) ( c(1 cal./1g 1(C) ( (T(change in temp. (C) c = 1.00 cal/g (C or c = 4.18 J/g (C Conclusions and Questions: 10. (a.) q = 135.83 g ( 1cal.( 25.

5(C g ( C q(heat) = 3,463.7 cal. (b.) q = 135.83 g ( 4.18 J ( 25.5 (C g ( C q(heat) = 14,178.1 J 11. (a.) 3,463.7 cal. 0.76 g Heat of blaze of the candle = 4,557 cal./ gram of wax burned (b.) 14,178.1 J ! 0.76 g Heat of combustion of the candle = 18,655.4 J/ gram of wax burned 12. One solution of founder could be that some of the heat from the candle could have been released into the ratiocinative argument and not absorbed by the can. Another source of computer error could be that the water could have not absorbed whole the heat from the can.If you want to get a full essay, nine it on our website: OrderEssay.net
