Question

Use the table below to identify the type of metal in the object WEC Wwter 134 10 Copper ONS 0.0920 0.214 0.128 0.306 00125 Unknown metall 29.58 180°C 125 g 20.00°C Mass of metal (8) Initial temperature of metal ["C) Mass of water in the calorimeter (e) Initial temperature of water in the calorimeter (°C) Final temperature of water and metal ("C) Change in water temperature (AT . C) Energy absorbed by water (www.) Energy released by metal ( 1) Change in metal temperature (ATC) Specific heat of the metal (l/g °C) identity of metal Show your work below:

Final Temperature is 125 g

Answer 1

sensible heat is given by = mo Tf-Ti) where m= mass (gm) - Cp- specific heat of material (5/9°c) DT= Temperature deffence (OC) A Mass of Metal = 29.5g B.) Mass of water = 180.0 C d> intial Temperature of water = 20°C Given ( Mass of water = 125 gm es final temperature of waler and metal= 125 °C 1 f) Change in water temperature Ota Tf - Ti =(125°C – 20°c ) = 105°C Is Energy absorbed by water = ma cow (OT) =1259m x 4.184 7/9°C X 105° Pab. = 54915 I hs Energy released by metal= energy absob by waleš 80 Preleased 549155 Change in metal temperature = ATE 180-185 - Ima 55°C Is specefic heat of metal. Pabe mm Cpm (atm) Sugis = 29.5 pro (550) (pm = 33.84 f/gec → check your final temperature again.
