a variety of non-metal materials - fiberglass, styrofoam, rubber -- are thermal insulators; that is, when there is a temperature difference across their ends, they do not transfer energy efficiently from the higher temperature end to the lower temperature end. will a thermal insulator generally 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

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
