- Homework Statement
- For most solids at room temperature, the specific heat is determined by oscillations of the atom cores in the lattice (each oscillating lattice site contributes 3kT of energy, by equipartition), as well as a contribution from the mobile electrons (if it's a metal). At room temperature the latter contribution is typically much smaller than the former, so we will ignore it here. In other words, you can reasonably estimate the specific heat simply by counting the number of atoms!

Use this fact to estimate the specific heat of copper (atomic mass = 63.6), given that the specific heat of aluminum (atomic mass = 27.0) is 900 J/kg-K.

- Relevant Equations
- Q = mc(delta T)

I thought it might me a ratio of the atomic masses.

27 / 63.6 = x / 900

x = 382 J/kg-K

27 / 63.6 = x / 900

x = 382 J/kg-K
