Data Collection and Processing
Qualitative
The temperature of the water inside the calorimeter decreases   after the melting period
The volume of water inside the calorimeter increases after   the ice fully melted.
Quantitative
Mass of inner cup = (45.70 ± 0.01) g     Trial 1
Mass of inner cup + water = (107.26 ± 0.01) g
Initial temperature of water = ( 30.0 ± 0.5) °C
Final mass of inner cup + water = (114.03 ± 0.01) g
Temperature of water after melting of ice = ( 21.0 ± 0.5) °C
Trial 2
Mass of inner cup + water = (108.25 ± 0.01) g
Initial temperature of water = ( 31.5 ± 0.5) °C
Final mass of inner cup + water after melting of ice = (117.03   ± 0.01) g
Temperature of water after melting of ice = ( 20.0 ± 0.5) °C
*Table 1 :* Processed data of the experiment
Sample calculations involved are as shown below:
= 6.77 g
Uncertainty of mass of ice = 0.01 + 0.01     Trial 1 :
(0.06156)(4200)(9) = (0.00677) l
_ l = 343.717 kJ_ kg-1
Uncertainty :
Trial 2 :
(0.06255)(4200)(11.5) = (0.00878) l
_ l = _344.096 kJ kg-1
= 100% - ( Experimental valueTheoretical value×100 )
= 100 % - ( 60434200×100 )
= 44 %

CONCLUSION AND EVALUATION
Specific heat capacity is commonly defined as the amount of heat energy required to increase the temperature of 1 kg of substance by one degrees Celsius or one Kelvin. In this experiment however, the specific heat capacity of water is required to be calculated. Water is known to be a very good cooling agent mainly because of its high specific heat capacity and the ability to absorb and irradiate great amounts of heat without increasing the temperature of it. Conversely, needing a high amount of energy to enter or leave the system to increase its temperature. The equation that is used in the...
