EXPERIMENT- Calorimetry REPORT FORM Date: Material of Calorimeter: Aluminum Specific heat of calorimeter: Specific Heat (data taken from Video) Mass of empty Calorimeter (Mc) 58grams Mass of calorimeter + water 156 g Mass of water (M.) 98 9 Mass of metal (Mm) Initial temperature of cold water (T) Temperature of boiling water and metal (T) Final equilibrium temperature (7) Calculated value of specific heat Apparent nature of metal: Brass Percent error: Latent Heat (data taken from Video) Mass of empty Calorimeter (Mc) Mass of calorimeter + water Mass of water (M) Initial temperature of water (Twi) Final equilibrium temperature (7) Mass of calorimeter + water + melted ice Mass of ice Calculated value of Latent Heat: Book value of Latent Heat of ice: 336 Percent error: 336 J/g leke g 27.1 č 0.89 J/g °C 100 °C 30.0 °C Book value of specific heat: 56 9 136 9 80 9 25.5C 270 C X 18 g 0.380 J/gk
CALCULATIONS 1) Calculate the specific heat from equation 1 2) Calculate the latent heat from equation 2 3) Calculate the percent errors. Percent difference = 100 % x [Actual-measured value]/actual value
Calculations. Then in Tiv MEN (Mw Cw+Mecc) x (T-Twi) + Mm Cm x (T-Tm)-0 1 Where: 'M' is mass. 'e' is specific heat, and 'T' is temperature. The subscript 'm' refers to metal, 'w' to water, 'c' to calorimeter. 'i' to initial and 'f' to final. The Latent heat is the amount of heat required to change unit mass of a substance from solid state to liquid state, or from a liquid state to gaseous state, without a change in temperature. The latent heat of fusion is the latent heat when a solid turns to liquid. Its SI units are J/kg. In the experiment, we shall measure the temperature of the calorimeter plus water before and after mixing it with ice. The masses and temperatures of the water before and after mixing will be measured. Then, the latent heat will be found from: (My Cw+McC) x (Tj-Twi) + Mice Cu (T-0) + Mice Lice=0 2
