Aim: Perform an sample to determine the latent hotness of uniting for draw. Materials:         Calorimeter                 Celsius Thermometer                 Platform balance                 Kettle                 Milk scrap cubes                 Stopwatch                 Hot Water                 Procedure: The copper loving instill was weighed and its mass was and hence recorded. The kettle was then utilize to churn water and this water was poured into the copper instill. The mass of the form positive the hot water was calculated and recorded. The copper cup was then lay in the insulated container. The waters temperature was then recorded. The temperature of the milk grouch was then recorded. The ice cub was then placed in the water. The thermometer w as inserted and the temperature was taken at ten second intervals. This was done for two nose candy seconds to allow the final temperature to be reached. The cup was removed from the insulated container and placed on the platform balance. This procedure was restate twice more to get data for a add up of three trials. Analysis: From the fancy of thermal equilibrium the latent heat of fusion for milk was calculated from the data obtained from the decide out.
Q(lost) = Q(gained) Q(gained) = Q(milk ice + milk) = mc(ice)?T + mLf + mc(milk)?T Q(lost) = Q(water + cup) = m(cup)c(copper)?T + m(water)c(water)?T Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ! Â Â Â Â Â Â Â Â Â (Working shown on following page) From the latent heat of fusion calculated from the try it was observed that the avg. of the tests produced an Lf of approximately 3.0X10^5J/kg. Following the comparison of the calculated Lf from the experiment with the actual value Lf of milk, which is 2.8X10^5j/kg, it is found that the data from the experiment is comparatively accurate. Therefore, it can be concluded that there are little to no inconsistencies with the data that was gathered from the experiment. The...
