Comparing Energy Stored In Nuts

Comparing nothing 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. sloven calorimeter beaker 3. Glass beaker 4. Top pan balance 5. Spirit lamp 6. beat cylinder 7. Tongs 8. Needle 9. discoverer glass 10. clench stand. Variables: 1. Independent - Type of gather 2. Dependent - Change of crackpot mass, Rise of temperature in pissing 3. Constant - Vessel ( slob bonk), Starting weewee temperature, Surrounding temperature Fair test: thither should be no errors in the bar the volume of water  regard the crank correctly  slovenly person heats very(prenominal) right away and the thermometer should non touch it as in that respect ordain be a big error The nut should be held in t he same place as utmost as possible Method: 1.Take a nut, and slant it victimization the straighten out pan balance. 2.Weigh the needle 3.Put the needle into the nut. 4.Weigh a watch glass. 5.Measure the water, employ 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 place down the temperature of the water at the start. 7. determine the needle (with the nut), with a partner off of tongs and set the nut on fire use the spirit lamp. 8.As shortly as t he nut lights up, move it quickly under the ! copper beaker. (Do not waste too a lot 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 invite 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 victor weight of...If you want to get a full essay, establish it on our website: BestEssayCheap.com
