Webberyllium 1.82 J/ (g°C) calcium 0.653 J/ (g°C) copper 0.385 J/ (g°C) gold 0.129 J/ (g°C) Set the energy gained by water equal to the energy lost by aluminum and the sum of the changes in temperature equal to 80 degrees. Solve these two simultaneous equations for change in temperature. WebSolution: Comment: We must do two calculations and then sum the answers. 1) The first calculation uses this equation: q = (mass) (Δt) (Cp) This summarizes the information needed: Δt = 75.0 °C The mass = 45.0 g Cp= 4.184 J g¯1°C¯1 2) Substituting, we have: q = (45.0 g) (75.0 °C) (4.184 J g¯1°C¯1) q = 14121 J = 14.121 kJ
