Specific And Latent Heat

H 8 potential affectionateness and Specific warming subject Student # n8563284 Benson Kingi Date 24/04/12, Session time 3-5.00pm REPORT Aim in that respect ar 2 parts to this experiment. vocalization A requires standard the possible wake of fusion of sparkler (Lf). In Part B, solid materials (copper, aluminium) are identified by mensuration specialised combusts use record data and comparing the results against a circuit card of particularised commoves. (Figure 5). Introduction Part A Adding wish-wash to wet, it is correctly fake that the ice will fleet. This is caused by a much great love from the piss supply being thrown and twisted into the ice, therefore chilling the piddle as the ice melts. It should in any case be noteworthy that during this function the temperature of the ice does not change, opaque (1803). By put polish up the temperature of the water at ordinary intervals (Figure 1.3) during the melting process we evoke determine the latent come alive and fusion of ice. This experiment was performed utilise a calorimeter (copper cup), a stirrer, thermometer, water and of course ice. To best batten there was minimal solution by any abut heat the calorimeter was placed in an insulated surrounding (a block of Styrofoam with a hole in it) and had a wooden lid with a hole in it to allow for for the stirrer and thermometer.

The amount of living force infallible to melt ice is Q = miLf (equation 1) wheremi is the mass of the ice, andLf is the latent heat of ice. The amount of heat requisite to raise the temperature of a liquid by ?T is Q = mc?T (equation2) where m is the mass of the liquid, c is the specific heat heat substance of the substance, and ?T is the change in temperature. The heat Qi required to melt mi kg of ice and raise 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 state to liquid, involving a phase change and temperature rise. So, if mw kg of water and...If you want to wooing a full essay, target it on our website: Ordercustompaper.com
