Question

Which of the following has a very high thermal conductivity?

(a) Concrete

(b) Glass

(c) Wood

(d) Copper

The question was posed to me by my college director while I was bunking the class.

My question comes from Properties of Fermentation Vessels in chapter Fermentation System & Management of Fermentation Technology

Answer 1

The correct answer is (d) Copper

For explanation I would say: Copper has a very high thermal conductivity which is used as a fabricated material in the construction of fermentation vessel. It is strong, durable, expensive, easily worked, and cleaned. Glass, concrete, and wood have very low conductivity.
