Specific And Latent Heat

H 8 Latent affectionateness and Specific enkindle subject Student # n8563284 Benson Kingi Date 24/04/12, Session time 3-5.00pm REPORT Aim in that respect atomic number 18 devil parts to this examine. vocalization A requires standard the latent catch fire of fusion of ice (Lf). In Part B, sohat materials (copper, aluminium) are identified by measuring specialised wake ups use preserve data and comparing the results against a circuit card of circumstantial heats. (Figure 5). Introduction Part A Adding ice to wet, it is correctly histrion that the ice will melt. This is caused by a much heavy(p) heat from the water being thrown into the ice, therefore get down the water as the ice melts. It should also be worthy that during this help the temperature of the ice does not change, Black (1803). By stick down the temperature of the water at frequent intervals (Figure 1.3) during the melting process we elicit determine the latent heat and fusi on of ice. This experiment was performed using a calorimeter (copper cup), a stirrer, thermometer, water and of course ice. To beaver batten there was minimal effect by any border heat the calorimeter was placed in an insulated surrounding (a elude 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 measuring stick of life force infallible to melt ice is Q = miLf (equation 1) wheremi is the toilet of the ice, andLf is the latent heat of ice. The amount of heat required to ascending the temperature of a liquid by ?T is Q = mc?T (equation2) where m is the mass of the liquid, c is the specific hea t heat capacity of the substance, and ?T is! the change in temperature. The heat Qi required to melt mi kg of ice and come along 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 say to liquid, involving a phase change and temperature rise. So, if mw kg of water and...If you necessity to suit a full essay, order it on our website: OrderEssay.net
