Does the value of thermal conductivity depend on the dimension of the specimen?
Thermal conductivity is an intensive property. It is inherent in the material but not dependent on the amount of material. This should not be confused with the rate of heat conduction which can depend on the dimensions of a material. There is one case where the thermal conductivity might depend on the dimension of the material - when the conductivity is not uniform with direction, i.e. where conductivity laterally is different from conductivity longitudinally. When the orientation of the material changes the conductivity, the dimensions can have an effect on the apparent bulk thermal conductivity.
What is used to describe how well various substances conduct thermal energy?
thermal conductivity The term for how substances conduct thermal energy is thermal conductivity.
What is thermal and electrical conductiuity?
Thermal conductivity is the ability of a material to conduct heat, while electrical conductivity is the ability to conduct electricity. Materials with high thermal conductivity can transfer heat quickly, while those with high electrical conductivity allow electricity to flow easily. Both properties are important in various applications, such as in electronics and thermal management.

Do elements that have high electric conductivity also have high thermal conductivity?
Not necessarily. While there is some correlation between electrical and thermal conductivity in metals, there are exceptions. For example, diamond is a good thermal insulator despite being a good electrical insulator. Additionally, materials like ceramics can have low electrical conductivity but high thermal conductivity.
