Chapter 2- States of Matter Flashcards
states of matter
a state of matter is one of the distinct forms that matter takes on
solid
firm and stable in shape; not liquid or fluid
liquid
having a consistency like that of water or oil, i.e., flowing freely but of constant volume.
gas
an air like fluid substance which expands freely to fill any space available, irrespective of its quantity.
surface tension
the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
viscosity
a quantity expressing the magnitude of internal friction, as measured by the force per unit area resisting a flow in which parallel layers unit distance apart have unit speed relative to one another.
volume
the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
pressure
the continuous physical force exerted on or against an object by something in contact with it.
Boyles law
Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant.
Charles’s law
pressure and temperature is the same
melting
when a solid goes to a liquid
evaporation
Evaporation is the process of a substance in a liquid state changing to a gaseous state
boiling
liquid to a vapor
condensation
gas to liquid
sublimation
solid directly to gas
