A copper of calorimeter weighs 100g when empty and 200g when half filled with water at 20 degree celcious 5g of steam is pass into the calorimeter untill the final steady of temperatur 54 degree celcious is reach neglecting heat lost to the surrounding calculate the sp.l.h of the steam take sp.c.h of water 4200j/kg/k and sp.h.c of calorimeter 400j/kg/j
