Part 2. Fill in the Blank Specific Heats of Selected Metals Metal Smetal J/gC Metal Smecal Jig C 0.449 0.444 0.226 1.02 Al 0.901 Fe Cu 0384 Ni0 Si Zn Sn Mn 0.389 1) Use the above table (which is a list of specific heat constants [c] for various metals) for the following question: of a 200 gram piece of metal by Vs c. 15.0 oC. The metal in this heating had a specific heat constant (c) of- which means it's identity is 2) A solution that absorbs at the wavelength of 620 nm will absorb the color range reflect the color bveUse the colorwheel below for reference orange

Explanation / Answer

1)

heat takes = 2133 J

mass of sample = 200 g

temperature rise = 15.0 oC

Q = m Cp dT

2133 = 200 x Cp x 15

Cp = 0.711 J / g oC

specific heat = 0.711 J/g oC

identity of metal = Si (silicon)
