the gaseous state of a substance that is normally a solid or liquid at room temperature
vapor
describes particles and their interactions in all states of matter
kinetic molecular theory
matter with a definite volume but no definite shape
liquid
Which is the 2 main factors determining the state of matter?
Particle motion and force
This type of matter allows particles to slide past each other.
Liquid
describes the relationship between the volume and pressure of a gas at constant temperature
Boyle's Law
describes the relationship between the temperature
and volume of a gas at constant pressure

the gaseous state of a substance that is normally a solid or liquid at room temperature
vapor
a liquid’s resistance to flow
viscosity
uneven forces acting on the particles at the surface of a liquid
Surface Tension
The amount of force applied per unit of area is
pressure
matter with no definite volume and no definite shape
