Final answer:
In a gas, tiny particles are spread out with no regular arrangement and move in a rapid and random manner, with their motion impacted by temperature. They experience elastic collisions with one another and the container, and there are no interactive forces between them.
Step-by-step explanation:
Particle Arrangement and Behavior in a Gas
The arrangement of particles in a gas is characterized by highly separated tiny particles that are in continuous, rapid, and random motion. These gas particles have large amounts of empty space between them, and they collide elastically with each other and the walls of their container, which means there's no net energy loss from the collisions. There are no interactive forces such as attraction or repulsion between the particles, and as a result, gas fills the entire volume of its container, adopting its shape. The movement of gas particles is influenced by temperature, with higher temperatures increasing the average speed of the particles.
Effects of Temperature
The kinetic energy of gas particles and, subsequently, their speed is directly related to the temperature of the gas. As the temperature rises, particles move faster, which also increases the frequency and energy of their collisions with each other and the container surfaces.
