1 x cice x T = 1 x cwater x (10°-T)

aragorn this is not the right method..

first you have to consider if whole of ice melts..

if it does, then L.1 < 10. Cwater

then the remaining heat will be used to balance the temperature..

yes bhaiya is ABSOLUTELY correct!!

i used to folow this method ... and it betrayed me .....

then i left it..

lat heat f fusion in ice : 3.4 X 10^5 J/Kg

amount of heat releasesd by water in coming from 10 to 0 deg C.

= 10 X 4200 X 1 = 42000 J.

this is less than the amount required to melt the whole of ice (340000 J)

so the final temperature is 0°C.

and at that temp, some ice is still left.

if u need to find the amount of ie left,

m' X 340000 = (340000 - 42000) =>m' = amount of ice at 0 degC.
