Question

when 10 grams of ice at -20 degree Celsius is mixed with 10 gram of water at 50 degree Celsius the amount of ice melted is
​

Answer 1

Explanation:

Heat given by water =100×1×800=8000cal

Heat taken by ice =8000cal=m×80

On solving we get m=100gm

So amount of ice which does not melt =150−100=50gm.
