Homework Statement
steam at 100C is added to ice at 0C find the amount of ice melted and the final temperature when the mass of steam is 10g and the mass of ice is 50g
Homework Equations
Q=mcdT
Q=ML
The Attempt at a Solution
Qmelt=MiciT+MiLf
=0.05(2090)(100C)+(0.05)(3.33x10^5)
=27100J
27100+Micw(Tf-0C)+Mscw(Tf-20C)=0
Tf=[100(0.01)(4190)-27100]/[(0.05)(4190)+(0.01)(4190)]
=-91
am i doing this question correctly? cause in the question it askes for the final temperature but i don't think the finall temperture would be -91 when it starts out with 100C and 0C.. also I am not sure how to find the amount of ice melted can someone help?
i thnk it has something to do with finding out the final temperture then plug it into Q=mcdT and you solve for m?? is this correct?.. but i still don't know how to find the final temperture correctly.. please help
