Question

do thermal conductors have low conductivity ?

Answer 1

All thermal conductors have conductivity. "Low" is kinda arbitrary... In general, if one says something is a thermal conductor, it has "good" or "high" thermal conductivity.

Answer 2

so it not an answer right i know they have low air pockets ,high conductivity ,and often metals but do they have low latent heat ?

Answer 3

Yes. Latent heat is how much heat, or energy you need to dump into the material to get it to change its temperature by one unit, or degree. Something that is a good thermal conductor will require less heat to raise it's temperature than something that is a poor conductor. So something with high conductivity will require less heat, and therefore have low latent heat.

Answer 4

The higher the temperature of the metal the more electrons it can hold, however it will have a lower conductivity. Metals are good thermal conductors and they are conductors of electricity, so no, GENERALLY good conductors of electricity are also good conductors of thermal energy, also.
