Homework Statement
An aluminum vessel of 500 gr contains 117.5 gr water at 200C. a piece of iron of mass 200 gr and 750C is thrown inside. what's the final temperature and the water equivalent of the vessel.
Homework Equations
Specific heat of aluminum: 0.217
Specific heat of iron: 0.113
The Attempt at a Solution
##(500\cdot 0.217+117.5)(t-20)=200\cdot 0.113 (75-t)\rightarrow t=25^0##
The answer should be 230C.
The water equivalent:
##500\cdot 0.217=m=108.5 gr##
The answer should be 110 gr
