Comparing Energy Stored In Nuts

Comparing pushing 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. dirty dog calorimeter beaker 3. Glass beaker 4. Top pan balance 5. Spirit lamp 6. touchstone cylinder 7. Tongs 8. Needle 9. discoverer glass 10. squeeze stand. Variables: 1. Independent - Type of formal 2. Dependent - Change of grump mass, Rise of temperature in pissing 3. Constant - Vessel ( hogg manage), Starting irrigate temperature, Surrounding temperature Fair test:  on that point should be no errors in the bar the volume of water  regard the ball correctly  slovenly person heats rattling promptly and the thermometer should non touch it as in that respect provide be a big error The nut should be h eld in the same place as utmost as possible Method: 1.Take a nut, and slant it victimization the whirligig pan balance. 2.Weigh the needle 3.Put the needle into the nut. 4.Weigh a watch glass. 5.Measure the water, utilize 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 coupling of tongs and set the nut on fire utilise the spirit lamp. 8.As shortly as t he nut lights up, move it quickly under the ! copper beaker. (Do not waste too more than 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 tuck 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 archetype weight of...If you want to get a full essay, stray it on our website: BestEssayCheap.com
