Thermal Properties of Matter

The SI unit of thermal conductivity is:

  1. A.J m K−1\mathrm{J\,m\,K^{-1}}
  2. B.J m−1 K−1\mathrm{J\,m^{-1}\,K^{-1}}
  3. C.W m K−1\mathrm{W\,m\,K^{-1}}
  4. D.W m−1 K−1\mathrm{W\,m^{-1}\,K^{-1}}✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
