a 4kg iron hammer is initally 700 degree celcius is droppped into a bucket containing 20kg of water at 25degree celcius. what is the final temperture

2. Relevant equations

q=mc(delta)T

3. The attempt at a solution

m1=4kg

m2=20kg

T1=700=973K

T2=25=298

i know the system is in equilibrium but i dont know how to solve it correctly.. so heres my shot at it

Q=mc(delta)T

=(4)(449J/kgK)(Tf-973)=(20)(4190J/kgK)(Tf-298)

i think i'm doing this question wrong because .. when i solve for Tf i get a negative number of -288.66K

help?
