A 235-g sample of a substance is heated to 320 ∘C and then
plunged into a 105-g aluminum calorimeter cup containing 175 g of
water and a 17-g glass thermometer at 10.5 ∘C. The final
temperature is 35.0∘C. The value of specific heat for aluminium is
900 J/kg⋅C∘ , for glass is 840 J/kg⋅C∘ , and for water is 4186
J/kg⋅C∘ . Part A What is the specific heat of the substance?
(Assume no water boils away.) Express your answer...

A cube of ice is taken from the freezer at -9.5 ∘C and placed in
a 95-g aluminum calorimeter filled with 320 g of water at room
temperature of 20.0 ∘C. The final situation is observed to be all
water at 15.0 ∘C. The specific heat of ice is 2100 J/kg⋅C∘, the
specific heat of aluminum is 900 J/kg⋅C∘, the specific heat of
water is is 4186 J/kg⋅C∘, the heat of fusion of water is 333
kJ/Kg.
