- Kinetic Molecular Theory: A scientific theory that explains the behavior of gases, stating that particles in a gas are in constant, random motion and exhibit elastic collisions.
- Elastic Collisions: Collisions between gas particles that occur without any loss of kinetic energy, allowing them to bounce off each other.
- Compressibility: The ability of a gas to decrease in volume under pressure, due to the large spaces between particles.
- Random Motion: The unpredictable movement of gas particles in all directions, contributing to their diffusion.
- Diffusion: The process of gas particles spreading out and mixing due to their random motion, moving from areas of high concentration to areas of low concentration.
- Temperature: A measure of the average kinetic energy of particles in a substance, influencing the speed of gas molecules.
- Absolute Temperature: The temperature measured on the Kelvin scale, which starts at absolute zero where all molecular motion theoretically ceases.
- Molecular Characteristics: Specific features of molecules, such as mass and structure, which can affect how they interact and behave.
- Force of Attraction: The interparticle forces that can occur between gas molecules, although negligible in ideal gases.
- Translational Motion: The movement of molecules from one position to another, contributing to the flow and behavior of gases.
- The kinetic molecular theory describes how particles in a gas are in constant motion.
- In elastic collisions, gas particles lose kinetic energy upon contact.
- Gases are highly compressible due to the large spaces between their particles.
- Random motion refers to the predictable paths taken by gas molecules.
- Diffusion is the movement of gas particles from an area of low concentration to an area of high concentration.
- Temperature is directly related to the average kinetic energy of gas particles.
- Absolute temperature cannot be below zero on the Kelvin scale.
- The mass of gas particles has no impact on their behavior and interactions.
- In gases, the force of attraction between particles is significant and affects their movement.
- Translational motion refers to the rotation of gas molecules in place.
- The average kinetic energy of gas particles decreases as the temperature increases.
- According to kinetic molecular theory, all molecules at the same temperature have the same kinetic energy.
