Prompt: Post a brief summary of the lab and how you were able to identify your unknown metal. Indicate your calculated specific heats for the metal. Provide the identification of the metal you tested.
Summary: The goal of the lab was to determine metal by finding the specific heat. This was done by measuring the temperature change of the rock in boiling water to that same rock in room temperature water and then calculating the specific heat. This helped us to become more comfortable identifying and working with specific heat.
Data
Mass of styrofoam cup: 7.90 g
Mass of cup + water: 300.75 g
Mass of water: 292.85 g
Initial temp of water in cup: 20.5 degrees celsius
Initial temp of metal in boiling water: 96.5 degrees celsius
Final temp of metal and water: 26.5
Mass of metal alone: 249.52
My partner and I concluded that the metal we worked with was steel.
