Chapter 10 Flashcards
Based on the idea that particles of matter are always in motion
Kinetic-Molecular Theory
A hypothetical gas that perfectly fits all the assumptions of the kinetic-molecular theory
Ideal gas
A collision between gas particles in which there is no net loss of total kinetic energy
Elastic collision
Spontaneous mixing of particles of two different substances caused by their random motion
Diffusion
Process by which gas particles pass through a tiny opening
Effusion
A gas that doesn’t behave completely according to the assumptions of the kinetic-molecular theory
Real gas
A substance that can flow and takes the shape of its container
Liquid
A force that tends to pull adjacent parts of a liquid’s surface together, thereby decreasing surface area to the smallest possible size
Surface tension
The attraction of the surface of a liquid to the surface of a solid
Capillary action
How a liquid or solid changes to a gas
Vaporization
How particles escape from the surface of a nonboiling liquid and enter the gas state
Evaporation
The physical change of a liquid to a solid by removal of energy as heat
Freezing (or solidification)
A solid consisting of crystals
Crystalline solid
A substance in which the particles are arranged in an orderly, geometric, repeating pattern
Crystal
A solid in which the particles are arranged randomly
Amorphous solid
