Q)..Steam at 100^C is passsed through a hole drilled in a 2kg of ice at 0^c.After some time, 1.5kg at ice is left and 562.5g of water at 0^ C is formed. Calculate the specific latent heat of vaporization of water ?????

m of ice = 2 kg, left ice = 1.5 kg, melted ice = 500 g
total water at 0 degree = 562.5 g----- a
water fm ice = 500 g ---- b
=> water at 0 degree from steam = a - b = 62.5.

heat lost by steam = heat gained by ice
m steam * L steam + m steam *c WATER* DT WATER FRM STEAM=

m ice * L of ice

62.5* L + 62.5 * 4.2* 100 = 500 *336

L OF STEAM = (168000 - 26250 )/ 62.5 = 2268 J/g
