Question

Which of the following aspects of kinetic-molecular theory explain why a plasma-based light doesn't get unbearably hot? Select all that apply.

a. Particles exchange energy through elastic collisions.
b. All particles are in constant random motion.
c. Particles are small.
d. Except during collisions, interactions between particles are negligible.

Answer 1

The aspects of the kinetic-molecular theory that explain why a plasma-based light doesn't get unbearably hot are: particles exchange energy through elastic collisions, all particles are in constant random motion, and except during collisions, interactions between particles are negligible. The correct options are a, b and d.

Step-by-step explanation:

The aspects of the kinetic-molecular theory that explain why a plasma-based light doesn't get unbearably hot are:

1. Particles exchange energy through elastic collisions. In a plasma, the particles collide with each other frequently, transferring energy without losing any of it.
2. All particles are in constant random motion. The high energy of the plasma particles prevents them from losing energy and getting too hot.
3. Except during collisions, interactions between particles are negligible. The lack of significant forces of attraction or repulsion between the particles in a plasma allows for minimal energy loss and the maintenance of a stable temperature.

Hence, Options a, b and d are correct.
