Formula for finding initial temperature

WebI am trying to solve the following heat transfer problem and am finding my current knowledge deficient for setting up my equations correctly: "You drop a 283-g silver figure of a polar bear into the 233-g aluminum cup of a well-insulated calorimeter containing 255 g of liquid water at 24.7°C. The bear\'s initial temperature is 98.1°C. WebBut it is quite easy to do a separate experiment to determine the total heat capacity of the calorimeter. You often set up your calculations like this: heat for water + heat for object + heat for calorimeter = 0. q₁ + q₂ + q₃ = 0. q₁ …
