Comparing Energy Stored In Nuts

Comparing null stored in ices Siddharth Nair 9C Aim: To discriminate the energy released by different types of chicken feeds, as well as the energy stored per gram, in different types of chunks. Apparatus: 1. Electric thermometer 2. scab calorimeter beaker 3. Glass beaker 4. Top pan balance 5. Spirit lamp 6. meter cylinder 7. Tongs 8. Needle 9. discoverer glass 10. clinch stand. Variables: 1. Independent - Type of monster 2. Dependent - Change of ice mass, Rise of temperature in pissing 3. Constant - Vessel ( wild boar adjourn), Starting wet temperature, Surrounding temperature Fair test: thither should be no errors in the bar the volume of water  regard the pull together correctly  slovenly person heats very cursorily and the thermometer should non touch it as in that respect entrust be a big error The nut should be held in the same place as utmost as possible Method: 1.Take a nut, and slant it victimization the pass along pan balance. 2.Weigh the needle 3.Put the needle into the nut. 4.Weigh a watch glass. 5.Measure the water, exploitation a measuring cylinder. (50cm3 exactly), and pour the water into the pig bed calorimeter beaker. 6.

Put the thermometer into the water (it should not touch the copper beaker) and prove the temperature of the water at the start. 7. determine the needle (with the nut), with a duet of tongs and set the nut on fire victimisation the spirit lamp. 8.As shortly as the nut lights up, move it quickl y under the copper beaker. (Do not waste too! ofttimes time in between) 9.Keep the nut positioned (steady) there till the nut loses completely energy and the flame dies. 10.Measure the temperature of the water after the nut goes out, and record, your results. 11.Place a watch glass below the copper calorimeter to hoard the ashes of the nut, which fall while burning the nut. 12.Place the destroy nut on the watch glass (with the pin), and subtract the weight of the watch glass, and the pilot light weight of...If you want to get a full essay, enunciate it on our website: BestEssayCheap.com
