Calculate the molar heat capacity of iron, A 45.61g piece of iron heated to 96.32˚C is transferred to a calorimeter containing 80.00g water initially at 24.91˚C. The temperature of the system at thermal equilibrium is 28.04˚C.
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 )
A piece of metal has mass 100 grams and an initial temperature of 100°C. It is placed in an insulated container of mass 200 grams which contains 500 grams of water at an initial temperature of 17.3°C. The container is made of the same material as the metal sample. If the final temperature is 22.7°C, what is the specific heat capacity of this metal? How many calories (1 cal = 4.186 J) are required to warm the metal sample by...
SPECIFIC HEAT OF A METAL Specific heat is an intensive property, which is the amount of heat required to raise the temperature of 1 gram substance by 1°C. Specific heat units areJ/g °C. Solve the following problems using your lecture notes: 1. When 8.50 g of metal, initially at 82 °C, is placed in 45 g water at 20°C, the final temperature of the metal and water is 22 °C. Calculate the specific heat of the metal in J/gºC. (specific...
