The specific heat of the metal sample can be calculated as:Specific heat = Energy absorbed / (Mass * Change in temperature)Specific heat = 100.0 J / (26.2 g * 8.5°C)Specific heat = 0.449 J/g°CThis value matches the specific heat of iron (Fe), which is 0.449 J/g°C. Therefore, the identity of the metal sample is Fe.
