kinetic theory of gases
Học thuậtThân thiện
Definition
- Noun:
- A physical theory describing gas behavior: The kinetic theory of gases is a fundamental model in physics. It explains the macroscopic properties of gases, such as pressure and temperature, by describing them as a large number of submicroscopic particles (atoms or molecules) that are in constant, random motion.
Usage Examples
- Noun:
- The kinetic theory of gases successfully explains Boyle's law.
- According to the kinetic theory of gases, the temperature of a gas is proportional to the average kinetic energy of its molecules.
- Understanding the kinetic theory of gases is essential for studying thermodynamics.
Advanced Usage
- "The assumptions of the kinetic theory of gases": This phrase refers to the foundational postulates of the theory, such as gases being composed of many small particles, the particles being in constant random straight-line motion, and collisions between particles being perfectly elastic.
- The derivation begins with the basic assumptions of the kinetic theory of gases.
Variants and Related Words
- Kinetic theory (n): A more general term for theories explaining the properties of matter based on the motion of its particles. The kinetic theory of gases is a specific application.
- The kinetic theory provides a bridge between mechanics and thermodynamics.
- Kinetic-molecular theory (n): A synonym often used interchangeably with "kinetic theory of gases."
- The kinetic-molecular theory is a cornerstone of chemistry.
Synonyms
- Kinetic-molecular theory of gases: An exact synonym.
- Molecular theory of gases: A closely related term emphasizing the molecular nature of the particles.
Related Phrases
- Derived from the kinetic theory: Indicates a law or equation that is a mathematical consequence of the theory's principles.
- The ideal gas law can be derived from the kinetic theory.
- Application of the kinetic theory: Refers to using the theory to explain or predict a specific phenomenon.
- The process of diffusion is a direct application of the kinetic theory.
Noun
- (physics) a theory that gases consist of small particles in random motion
