Comparing energy 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. squealer calorimeter beaker
3. Glass beaker
4. Top pan balance
5. Spirit lamp
6. Measuring cylinder
7. Tongs
8. Needle
9. discoverer glass
10. Clamp stand.
Variables:
1. Independent - Type of nut
2. Dependent - Change of nut mass, Rise of temperature in pissing
3. Constant - Vessel ( pig bed), Starting water temperature, Surrounding temperature
Fair test:
There should be no errors in the bar the volume of water
regard the nut correctly
slovenly person heats very quickly and the thermometer should non touch it as in that respect will 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 top pan balance.
2.Weigh the needle
3.Put the needle into the nut.
4.Weigh a watch glass.
5.Measure the water, using 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 record the temperature of the water at the start.
7. determine the needle (with the nut), with a pair of tongs and set the nut on fire using the spirit lamp.
8.As shortly as the nut lights up, move it quickly under the copper beaker. (Do not waste too much 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 collect 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 original weight of...If you want to get a full essay, order it on our website: Ordercustompaper.com
