applications?
a) Ductility
b) Electrical conductivity
c) Thermal conductivity
d) Strength

Answer 1

Answer: Thermal Conductivity

Explanation:

Answer 2

Answer:

Thermal conductivity

Explanation:

Thermal conductivity is a measure of the quantity of heat that flows through a material. It is measured as one degree per unit of time, per unit of cross-sectioned area, per unit of length. Materials with low thermal conductivity may be used as insulators, those with high thermal conductivity may be a heat sink.
