Metals are good thermal conductors - that is, when there is a temperature difference across their ends, they transfer
energy very efficiently from the higher temperature end to the lower temperature end. Based on this, would you
expect a thermal conductor generally to have a low specific heat capacity (closer to sand) or a high specific heat
capacity (closer to water) ?
A) Low specific heat capacity
B) High specific heat capacity
