Specific And Latent Heat

H 8 Latent affectionateness and Specific combust subject Student # n8563284 Benson Kingi Date 24/04/12, Session term 3-5.00pm REPORT Aim in that respect ar twain parts to this prove. vocalization A requires standard the latent love of fusion of ice (Lf). In Part B, so palpebra materials (copper, aluminium) are identified by measuring specialised incites use record data and comparing the results against a circuit card of specialized heats. (Figure 5). Introduction Part A Adding ice to wet, it is correctly imposter that the ice will melt. This is caused by a much large heat from the water being thrown into the ice, therefore cooling the water as the ice melts. It should also be famed that during this mold the temperature of the ice does not change, Black (1803). By jell 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 ice. This experiment was performed using a calorimeter (copper cup), a stirrer, thermometer, water and of course ice. To outmatch batten there was minimal effect by either border heat the calorimeter was placed in an insulated surrounding (a full point 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 substance of life force infallible to melt ice is Q = miLf (equation 1) wheremi is the fold of the ice, andLf is the latent heat of ice. The amount of heat required to tack together the temperature of a liquid by ?T is Q = mc?T (equation2) where m is the mass of the liqu id, c is the specific heat heat capacity of! the substance, and ?T is the change in temperature. The heat Qi required to melt mi kg of ice and originate 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 subject to liquid, involving a phase change and temperature rise. So, if mw kg of water and...If you destiny to suit a full essay, order it on our website: BestEssayCheap.com
