1.	A piece of ice balls from a height 'h' so that it melts completely .Only one quarter of the heat produced is absorbed by the ice and all energy . Of ice gets convertedin to heat during its fall. The value of h is : [" latent heat of ice is " 3.4 xx 10^(5) "J/kg and " g = 10 N/(kg) ]
Answer» 544 KM 136 km 68 km 34 km SOLUTION :` (mgh)/4 =mL ` ` :. H = (4L)/G` `= (4xx3.4 xx10^(5))/(10)` = 136 km
