Comparing Energy Stored In Nuts

Comparing get-up-and-go 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. rotter calorimeter beaker 3. Glass beaker 4. Top pan balance 5. Spirit lamp 6. metre cylinder 7. Tongs 8. Needle 9. discoverer glass 10. secure stand. Variables: 1. Independent - Type of chicken feed 2. Dependent - Change of junkie mass, Rise of temperature in pissing 3. Constant - Vessel ( bullshit manage), Starting water temperature, Surrounding temperature Fair test:  on that point should be no errors in the bar the volume of water  regard the en correctly  slovenly person heats real pronto and the thermometer should non touch it as in that respect go forth be a big error The nut should be hel d in the same place as utmost as possible Method: 1.Take a nut, and slant it victimization the top pan balance. 2.Weigh the needle 3.Put the needle into the nut. 4.Weigh a watch glass. 5.Measure the water, victimisation 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 memorialise the temperature of the water at the start. 7. determine the needle (with the nut), with a jibe of tongs and set the nut on fire apply the spirit lamp. 8.As shortly as the nut lights up, move it quickly under the copper beaker. (Do not was! te too much(prenominal) 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 take 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 genuine weight of...If you want to get a full essay, distinguish it on our website: BestEssayCheap.com
