Investigation 11
Specific heat capacity
Aim:
Investigate to determine the specific heat capacity of a metal cube provided
Apparatus:
-thermometer
-stirrer
-water
-calorimeter
-beam balance
-metal cube
-beaker
Procedure:
Using the normal equipment for Thermal Physics investigations, you are required to design and carry out an investigation to determine the specific heat capacity of a metal cube provide by teacher. Furthermore, you will need to compare your obtained value with published values, and confirm your identification of the metal by choosing a second physical property of the metal, and designing and carrying out an investigation to justify your findings.
Raw data:
Water= initial temperature: 24 , volume: 100ml Final temperature: 28
Metal Block= initial temperature: 100, mass:10g Final temperature : 28
Mass of calorimeter= 32g , Temperature same as water
Process data:
Cw = 4200J×ng-1°C-1 Cal = 900kg-1°C-1
Cw×Mw(tfw－tiw)+CaMc×(tfw-tiw)= CmMm(100－tfm) 900×32×(28－24)＋4200×100×(28－24)=Cm×10×(100－28)
Cm ＝ 115200 ÷70÷75
Cm ＝ 2194.2 J/kg
Limitation: The numbers on the calorimeter is not nicety enough which leads the data not accurate. These matter might be get influenced by air temperature.
Conclusion:
As you can see in the raw data, heat from the 100° metal cube has been transferred to the water by raising it initial temperature by 4°
Investigation 12
Latent heat of fusion of ice
Aim:
To determine the specific latent heat of ice by the method of mixture.
Apparatus:
-thermometer
-stirrer
-water
-calorimeter
-beam balance
-ice
Procedure: 1. Weight the calorimeter together with stirrer, m0 by a beam balance 2. Heat some water in a beaker to about 40°C 3. Half fill the calorimeter with this water and weigh again m1 4. Record the room temperature T0 5. Allow the water in the calorimeter to cool, Meanwhile, dry the cubes of ice between dry
