A 83.5 g sample of a metal alloy is heated to 88.1oC and it is then placed in a coffee-cup calorimeter containing 30.0 g water at 15.0oC. The final temperature of the metal + water is 25.3 oC. Calculate the specific heat of metal alloy, in J/(g oC), assuming no heat escapes to the surroundings or is transferred to the calorimeter. The specific heat of water is 4.184 J/(g oC).
A 24.5-g sample of an unknown metal is heated to 91.5°C and is placed in a perfectly insulated container along with 186.g of water at an initial temperature of 21.15°C. After a short time the temperature of both the metal and water become equal at 23.70°C. The specific Heat Capacity of water is 4.18 J/g/K in this temperature range. What is the specific heat capacity of the metal?
A 50.0 g piece of iron metal is heated to 200. oC. Then, the iron is placed into a water bath which is at 25.0oC. Eventually, both the iron and the water reach a temperature of 30.0oC. Determine the mass of water used in the experiment. (Specific heat for water is 4.184 J/g . oC ; the specific heat for iron is 0.449 J/g . C )
