1 kg ice at 0° C is mixed with 1 kg water at 10°C,then calculate final temperature.
39areh yaar ye aaj tuh kaise questions post karra??????????????????????
24kya karoon ?????????Mujhe thermodynamics ki A B C bhi nahin aati.......AAj shuru ki hai..........Meri hellp kar yaar...........
62aragorn 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..
1yes bhaiya is ABSOLUTELY correct!!
i used to folow this method ... and it betrayed me .....
then i left it..
1lat 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.
