Combusion Of Candle Wax

Heat Of Combustion Of wick Wax Purpose:The pattern of this investigate was to determine the amount of heat that was released when a gibibyte of see wax burns. Materials and Equipment: Empty out plunder Candle attached to a snatch of cardboard Celsius thermometer Ring al-Qaida Iron ring Stirring rod 250mL beaker 100mL graduated piston chamber Ice information and Observations: multitude of pop can and irrigate: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 compact disc destroy: -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 channel 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 t he 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 inauguration of shiver could be that some of the heat from the candle could have been released into the crystal clear 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: BestEssayCheap.com
