What best describes the motion of helium atoms in gaseous helium?
The helium atoms move quickly in all directions. This is cap
Which best describes the motion of iron atoms in solid iron?
In solid iron, the motion of iron atoms is characterized by vibrational movement around fixed positions within a crystalline lattice structure. These atoms oscillate due to thermal energy, but they do not have the freedom to move past one another, resulting in a rigid structure. As temperature increases, the amplitude of these vibrations increases, allowing for greater atomic movement while still maintaining the overall solid form.
Which best describes a kinetic theory?
atoms and molecules are always moving
Which best describes the motion of helium atoms in gaseous helium?
In gaseous helium, the motion of helium atoms is characterized by rapid, random movement. They move in straight lines until they collide with other atoms or the walls of their container, resulting in elastic collisions. The atoms exhibit high kinetic energy due to their low mass, which contributes to the gas's low density and high speed. Overall, the motion is chaotic and isotropic, meaning it is uniform in all directions.
What best describes all atoms of a particular element?

Which model best describes the particles of a solid and their motion?
The particles in a solid are arranged in a tightly packed, orderly structure. They vibrate in fixed positions around a mean position due to their attraction to each other. The model that best describes this behavior is the "rigid lattice" model.
