A piece of copper metal is initially at 83.0°C. It is dropped into a coffee cup calorimeter containing 30.0 9 of water at a temperature of 10.0°c. After stirring, the final temperature of both copper and water is 25.0°c. Assuming no heat losses, and that the specific heat (capacity) of water is 4.18 J/(g.), what is the heat capacity of the copper in J/K?
3. A75.0 g piece of copper metal is initially at 100°C. It is dropped into a coffee cup calorimeter containing 75.0 g of water a a rature of 20.0°c. Assuming that the only heat exchange is between the copper metal and the water (no heat is given to the calorimeter), what is the final temperature of the water. Specific heat of copper 0.387 J/goC
please help me. Thanks A piece of copper metal weighing 36.3 g is initially at 100.0 degree C. It is dropped into a coffee cup calorimeter containing 50.0 g of water at a temperature of 20.0 degree C. After stirring, the final temperature of both copper and water is 25.0 degree C. Assuming no heat losses, an that the specific heat capacity of water is 4.184 J/g degreeC, what is the specific heat capacity of the copper in J/g degreeC?
can you explain the correcr answer A metal alloy bolt is initially at 100.0°C. It is dropped into a coffee cup calorimeter containing 500 g of water at a temperature of 20.0°C Arter stirring, the fnal temperature of both bolt and water is 25.0°C. Assuming no heat losses, and that the specific heat (capacity of water is 4.18 J/gK what is the heat capacity of the bolt in J/K? A 2.79 JK 3.3.33 J/K G. 139 J/K 1.200 JK None...
