So here is my doubt -
10g of ice at -10C is added to 10g of water at 85C. What is the final temperature and amount of ice left in the system? (System is kept inside an ideal insulator)
This question may seem quite easy for many of the readers, but please help me with such questions as I find them tricky. I understand that this is a question which involves the application of the Q=mc(delta T) formula and that we have to equate the Q's of both ice and water in order to obtain the answer.
Another thing which is troubling me is that the answers to most of such questions that I have encountered is 0C, and this question is not an exception.
Please suggest me on how to go about such questions, and provide some conceptual clarity on the topic if possible. Thanks.
