When a 310-g piece of iron at 180 ∘C is placed in a 95-g aluminum calorimeter cup containing 250 g of liquid at 10∘C, the final temperature is observed to be 37 ∘C. The value of specific heat for iron is 450 J/kg⋅C∘, and for aluminum is 900 J/kg⋅C∘. Part A Determine the specific heat of the liquid. Express your answer using two significant figures. c c = nothing Jkg⋅C∘ Request Answer
