Kinetic Particle Theory and States of Matter

Flashcards covering key concepts related to the kinetic particle theory and states of matter.

Matter

Anything that has mass and volume.

Kinetic Particle Theory

Theory stating that all matter is made up of small particles that are in constant motion.

Solid

State of matter with closely packed particles in a fixed arrangement, vibrating in place.

Liquid

State of matter with loosely packed particles that flow and move in random zig-zag motion.

Gas

State of matter with particles that are far apart, moving freely and randomly.

Brownian Motion

Random movement of microscopic particles in a fluid due to collisions with surrounding molecules.

Melting Point

The fixed temperature at which a solid changes to a liquid.

Boiling Point

The fixed temperature at which a liquid changes to a gas.

Condensation

The process by which a gas changes to a liquid upon cooling.

Freezing

The process by which a liquid changes to a solid upon cooling.

Kinetic Energy

Energy possessed by a body due to its motion; related to temperature.

Diffusion

Movement of particles from a region of higher concentration to lower concentration.

Boyle's Law

Principle stating that the pressure of a fixed mass of gas is inversely proportional to its volume.

Pressure

Force acting over a unit area; measured in Pascals (Pa).

Heating Curve

Graph showing the temperature changes of a substance as it is heated.

Cooling Curve

Graph showing the temperature changes of a substance as it is cooled.

Relative Molecular Mass

Mass of a molecule compared to the mass of carbon-12, influencing rates of diffusion.
