The specific heat capacity of the objects can be calculated since the heat gained inside the reaction is equal to heat lost during typically the reaction. Due to the concept of thermal equilibrium we know that any time objects of differing temperature ranges are in contact along with the other person, in this situation the block, the and Aluminum calorimeter they are going to eventually transfer heat to the point at which they are the particular same temperature. By calculating the temperature before the particular blocks were added to the particular water and then once more when the temperature remains to be constant indicating equilibrium temp the change in temp was able to be calculated and taking advantage of this alongside with the mass in the objects and water plus calorimeter the specific warmth capacity could be computed using the Q=mc? Capital t formula.
With regard to the “ How cold is it in the freezer compartment? ” query an aluminum block was placed in the freezer and then placed directly into the in the calorimeter of which the temp had been recorded. The temperature of the water with the Aluminum obstruct was recorded until the regular temperature was reached. Together with this we can estimate the initial temperature associated with the aluminum block which often gives us the temperature of the freezer.
There were several restrictions inside the equipment used in order to carry out the method. Typically the scale used to gauge the mass of typically the aluminum calorimeter and drinking water only measured as much as 200g this was a major limitation as it just allowed for a small amount of drinking water to be added to the calorimeter which might have affected the temperature transfer as the immersed block may not experience been fully submerged as a result some heat may have got been lost to the particular air.
Found in moving the heated obstruct from the boiling water to be able to the calorimeter the obstruct could have lost warmth but this would get minimal because of the relatively higher Specific heat capacities associated with the blocks. When the block was moved into typically the calorimeter it was dropped into it and this triggered some water to sprinkle out which would decrease the mass of water inside the calorimeter which could influence the overall temperature switch. The value for that specific heat capacity (shc) of object one which had been Iron was compared to be able to the theoretical value regarding the shc of Flat iron and gave a 17. 6% difference this benefit is relatively high and may be due to questions in the measurements and mistakes manufactured from the procedure.
The % difference of object two has been very large at 23. 3% this could be as a result of random error but more likely due to the block not being fully submerged as I mentioned earlier. The benefit of the proportion difference regarding Object3 that was Copper has been relatively high at 18. 2%, So as to improve on the experiment a scale that measures up to a larger mass such as 500g. Another method to increase the experiment would be to add more drinking water to the calorimeter within order to insure the particular block was fully submerged. Another improvement that could be produced would be to not necessarily drop the blocks directly into the calorimeter and therefore minimize the risk of losing water after the particular mass was taken.
