Question

As temperature increases, molecular motion (i) ___________ and when temperature decreases, molecular motion (ii) ___________ But when the temperature becomes (iii) _________ molecular motion (iv) _____________. It is a (v) ___________ concept.This fact is defining (vi)____________ scale of temperature.

• A. (i) increases (ii) decreases (iii) zero
• B. (iv) ceases(v) theoretical(vi) Kelvin

Answer 1

1. According to Kinetic theory, Matter is composed of moving particles that can interact heavily with one another.
2. Particle motion is increased by increasing temperature and particle movement is reduced by reducing temperature.
3. At absolute zero, particle motion is completely stopped.

Hence, as temperature increases, molecular motion (i) increases, and when temperature decreases, molecular motion (ii) decreases But when the temperature becomes (iii) zero molecular motion (iv) ceases. It is a (v) theoretical concept. This fact is defining (vi) Kelvin's scale of temperature.
