Question

What is the value of Boltzmann’s constant?

(a) 8.314

(b) 1.38 * 10^-23

(c) 1.38

(d) 8.314 * 10^-23

I got this question in an online quiz.

I'm obligated to ask this question of Plastic Deformation in section Plastic Deformation and Creep in Crystalline Materials, Elastic, Anelastic and Viscoelastic Behaviour of Engineering Material & Metallurgy

Answer 1

The correct answer is (b) 1.38 * 10^-23

Explanation: Boltzmann’s constant is associated with the kinetic energy of gas particles. It is denoted as gas constant divided by Avogadro’s number. The value of Boltzmann’s constant is 1.38 * 10^-23 J K^-1 and that of the gas constant is 8.314 J mol^-1 K^-1.
