Copper has a specific heat of .390 j/gc. if 15.1 g of cu is heated to a tenoerature of 99.0 c and immersed in water. the resulting temperature of the cu was then 35.0. how much heat in j was transferred (added) to the water assume all heat us transferred to the water
A 17.0 g piece of aluminum (which has a molar heat capacity of 24.03 J/°C·mol) is heated to 82.4°C and dropped into a calorimeter containing water (specific heat capacity of water is 4.18 J/g°C) initially at 22.3°C. The final temperature of the water is 25.3°C. Ignoring significant figures, calculate the mass of water in the calorimeter.
Practice With Calorimetry And Heat 1. 75.0 g of cast iron was heated to 100°C and then plunged into 100 g of water at 23.0°C. Calculate the final temperature. Cast iron has specific heat of 0.46 J/gºc 2. A 25.0 g sample of an unknown metal at 99.5°C is placed into a calorimeter holding 50.0 g of water at 22.3°C. The final temperature was 26.2°C; what was the specific heat of the metal? 3. 30.0 g of water at 7.00°C...
A 92.5 g piece of aluminum (which has a molar heat capacity of 24.03]/°C-mol) is heated to 624°C and dropped into a calorimeter containing water (specific heat capacity of water is 4.18 J/g°C) initially at 19.2°C. The final temperature of the water is 135.2°C. Ignoring significant figures, calculate the mass of water in the calorimeter.
A 3.00-g sample of aluminum pellets (specific heat capacity=0.89 J/°C g) and a 18.50-g sample of iron pellets (specific heat capacity = 0.45 J/°C-g) are heated to 100.0 °C. The mixture of hot iron and aluminum is then dropped into 77.4 g water at 22.0 °C. Calculate the final temperature of the metal and water mixture, assuming no heat loss to the surroundings. Final temperature = 20.23 °C An error has been detected in your answer. Check for typos. miscalculations...
