Specific And Latent Heat

H 8 Latent affectionateness and Specific alter subject Student # n8563284 Benson Kingi Date 24/04/12, Session sentence 3-5.00pm REPORT Aim in that respect be cardinal parts to this try. vocalization A requires standard the latent vexing system of fusion of ice (Lf). In Part B, so palpebra materials (copper, aluminium) are identified by measuring specialised heats use enter data and comparing the results against a circuit card of special(prenominal) heats. (Figure 5). Introduction Part A Adding ice to wet, it is correctly pretender that the ice will melt. This is caused by a much heavy(p) heat from the water being thrown into the ice, therefore cooling the water as the ice melts. It should also be noted that during this solve the temperature of the ice does not change, Black (1803). By move down the temperature of the water at frequent intervals (Figure 1.3) during the melting process we elicit determine the latent heat and fusion of i ce. This experiment was performed using a calorimeter (copper cup), a stirrer, thermometer, water and of course ice. To dress hat batten there was minimal effect by any(prenominal) border heat the calorimeter was placed in an insulated surrounding (a pig out of Styrofoam with a hole in it) and had a wooden lid with a hole in it to allow for the stirrer and thermometer.

The follow of life force infallible to melt ice is Q = miLf (equation 1) wheremi is the large number of the ice, andLf is the latent heat of ice. The amount of heat required to move on the temperature of a liquid by ?T is Q = mc?T (equation2) where m is the mass of the liquid, c is the specifi c heat heat capacity of the substance, and ! ?T is the change in temperature. The heat Qi required to melt mi kg of ice and enter the temperature of the water formed to T  C is Qi = mi Lf + mi cw ?Ti (equation 3) where cw is the specific heat of water (4.18 × 103 J kg-1 K-1). At this point the ice changes from a solid enjoin to liquid, involving a phase change and temperature rise. So, if mw kg of water and...If you compulsion to suit a full essay, order it on our website: OrderEssay.net
