Question 3 • 26-27 - C - RUSD Chemistry in the Earth System

How does the motion of particles in the sun’s plasma compare to the motion of particles in a solid?

Answer
A
Particles in both the plasma and a solid move around to fill available space.
B
Particles in both the plasma and a solid are made up of fast-moving electrons and cations.
C
Particles in the plasma have low kinetic energy, but particles in a solid have high kinetic energy.
D
Particles in the plasma move randomly, but particles in a solid vibrate in one place.

Explanation

Particles in the Sun’s plasma have very high energy and move freely in random directions. In a solid, particles are held in fixed positions and mainly vibrate in place. Therefore, the correct choice is “Particles in the plasma move randomly, but particles in a solid vibrate in one place.”
