A 30.45−gstainless steel ball bearing at 103.2°C is placed in a constant-pressure calorimeter containing 121.9 g of water at 19.55°C. If the specific heat of the ball bearing is 0.474 J / (g·°C), calculate the final temperature of both the water and steel when they equilibrate. Assume the calorimeter to have negligible heat capacity.
A 60.5 g sample of metal at 100°C is placed into a calorimeter containing 123 mL of water at 21.3 °C. After mixing the water/metal mixture reaches a temperature of 25.2 °C. Determine the specific heat of the metal in J/g°C. Assume the calorimeter absorbs a negligible amount of heat. Specific heat of water is 4.184 J/g°C
The temperature of a piece of silver (specific heat Sag = 0.031j/g.°C) with a mass of 362 g decreased by 58 °C when it was added to a 98.56 g sample of water (specific heat of water Sw = 4.184 j/g °C) in a constant pressure calorimeter of negligible heat capacity. What is the final temperature of water if its initial temperature was 23.4 °C ?
An aluminium block is heated to 100 °C and then placed immediately in 100 g of water which is initially at a temperature of 25.0 °C in a coffee cup calorimeter. Once the system reaches thermal equilibrium, the temperature of the water that surrounds the block is 28.0 °C. Calculate the mass of the aluminium block. The specific heat capacity of Al is 0.900 J g^–1 K^–1 and for H2O is 4.184 J g^–1 K^–1
Enter your answer in the provided box. A 24.0-g sample of an unknown metal at 99°C was placed in a constant-pressure calorimeter containing 60.0 g of water at 24.0°C. The final temperature of the system was found to be 28.4°C. Calculate the specific heat of the metal. (The heat capacity of the calorimeter is 12.4 J/°C.) J/g. °C
A new metal alloy is found to have a specific heat capacity of 0.570 J/(g⋅∘C). First, 42.5 g of the new alloy is heated to 200. ∘C. Then, it is placed in an ideal constant-pressure calorimeter containing 65.0 g of water (Cs,water=4.184 J/(g⋅∘C)) at an initial temperature of 20.0 ∘C. What will the final temperature of the mixture be after it attains thermal equilibrium?
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?
