I have 252.2tf=57692

tf=228 K

Based off of the table the specific heats for Aluminum and Copper are. Al-0.900 and Copper-0.215

**Ray**, Monday, November 26, 2012 at 1:04pmI'm sorry for Aluminum its 0.215 and for Copper its 0.0922

**Ray**, Monday, November 26, 2012 at 1:13pmThe grams for Aluminum are 2.0e2 and the temperature for Aluminum is 2.2e2. The grams for water is 5.0e2.

**Elena**, Monday, November 26, 2012 at 1:33pmCu: m₁=0.1 kg, c₁=385 J/kg•K, T₁=460 K,

Al: m₂=0.2 kg, c₂=930 J/kg•K, T₂=220 K,

Water: m₃=0.5 kg, c₃=4183 J/kg•K, T₃280 K.

T=?

m₁c₁(T₁-T) = m₂c₂(T-T₂) +m₃c₃(T-T₃)

T= (m₁c₁T₁ + m₂c₂T₂ + m₃c₃T₃)/(m₁c₁ + m₂c₂ + m₃c₃)=

...=278.1 K
