Answer 1

Answer:

i dont know bahsjdjdbsah

Answer 2

15.72°C

Let the final temperature be t°C

By principle of calorimetry

Heat lost by water=Heat gained by Ice

=> mc(t2-t)=mL

=> 140×4.2(50-t)=60×336

=> 588(50-t)=60×336

=> (50-t)=34.285

=> t=(50-34.285)°C

=15.715°C

=15.72°C

Hope this helped. I know....most people on the internet are telling that the answer is 11°C, but I think it is wrong because what they have asked is for when the ice has melted not when it is heated after that.
