A 225-g sample of a substance is heated to 350 ∘C and then plunged into a 105-g aluminum calorimeter cup containing 195 g of water and a 17-g glass thermometer at 10.5 ∘C. The final temperature is 35.0∘C. The value of specific heat for aluminium is 900 J/kg⋅C∘ , for glass is 840 J/kg⋅C∘ , and for water is 4186 J/kg⋅C∘ . Part A What is the specific heat of the substance? (Assume no water boils away.)
Need help with my lab report for specific heat of unknown metal
Need help with my lab report for specific heat of unknown metal! I need to Find the Specific Heat of Al! I know its Q= M x Cs x Change in Temp I am getting a such a high number am just confused if its right. Here is what I got in Lab: Aluminum Mass of Metal (Mm): 6.128g Mass of water (Mw) : 25 mL Temp of water in calorimeter: 23.6 C Temp of metal in water-bath: 100 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
