Guida verificata passo dopo passo1
Understand that the kinetic molecular theory describes the behavior of gas particles, emphasizing their constant movement.
Recall that gas particles move in all directions and at various speeds, which is a key characteristic of their motion.
Identify the term that best describes this type of movement: 'Random motion' refers to particles moving unpredictably in all directions with different speeds.
Differentiate 'Random motion' from other terms: 'Diffusion' is the process of spreading out, 'Convection' involves bulk movement of fluids, and 'Brownian motion' describes the movement of particles suspended in a fluid due to collisions.
Conclude that the term 'Random motion' best fits the description of gas particles moving in all directions and at different speeds according to the kinetic molecular theory.
