Based on the kinetic theory, the statement that is true is:
"The particles of matter are in constant motion."
The kinetic theory of matter is a scientific explanation that describes the behavior of matter in terms of the motion of its particles. According to this theory, matter is made up of small particles (such as atoms or molecules) that are in constant motion. These particles possess kinetic energy, which is the energy associated with motion.
Therefore, the statement that matter consists of only charged particles or large molecules is incorrect according to the kinetic theory, as it does not take into account the existence of smaller particles. Additionally, the statement that the particles of matter have zero kinetic energy is also incorrect, as the kinetic theory asserts that particles in matter possess kinetic energy due to their motion.
