(i)Mass of condensed steam:
=(148-135)g
=13g
ii)Heat gained by water = mc?= 0.095 x 4200(52-24)=11172J?
Heat gained by calorimeter =mc?=0.06 x 390 x 28 =655.2J
Total heat gained =11172 + 655.2
=11827.2 Joules
iii)Heat given out by steam=Heat lost by condensing steam + heat lost by condensed steam
=0.013 x LV + 0.013 X 4200 X (100-52)
=0.13LV + 2620.8
iv)Total heat lost = Total heat gained
0.013LV + 2620.8 =11827.2
0.013LV =11827.2-2620.8
LV=9206.4/0.013
=708,184.6154Jkg-1
v)No heat loses
