Heat capacity of water is 4.20kJ/kg/K</p> <p>Some ices melts and the mass of water in the hollow is now 365g.</p> <p>&nbsp;</p> <p>Assuming no atmosphere-related heat gain, find specific latent heat of fusion of Ice.</p> <p>&nbsp;</p> <p>Here I did it this way:</p> <p>Q( Heat&nbsp;lost by 160g&nbsp;water) = Q( Heat&nbsp;gained by (365-160= 205g) of Ice)</p> <p>hence:</p> <p>ml(f) = ml(f)</p> <p>(0.205)( l(f) ) = (0.160)(4200)</p> <p>l(f) = 3.28kJ/kg/K</p> <p>&nbsp;</p> <p>Correct?</p> Sun, 04 May 2008 23:49:32 +0800 www.sgforums.com:2297:316507:8061771 limywv http://www.sgforums.com/forums/2297/topics/316507
