temperature
measure of all the avarage kinetic energy of all the particles in an object
kinetic energy
energy an object has due to it’s motion
vapor
gas state of a substance that is normally a solid or liquid at room tempature
Charles law
states that the volume of a gas increases with increasing tempatures if the pressure is constant
sublimation
change of state from a solid to a gas without going through the liquid
kinetic molecular theory
explanation of how the particles in matter behave. some basic ideas in this theory are: -small particles make up all matter -these particles are in constant, random motion -the particles collide with other particles, other objects, and the walls of their container -when particles collide no energy is lost
Thermal energy
total potential and kinetic energy of an object
Vaporization
two types of vaporization-evaporation-and-boiling
condensation
change of state from a gas to liquid
gas
matter that has no definate volume and no definate shape
Boyle’s law
states that pressure of a gas incraeses if the volume decreases and pressure of a gas decreases if the volume increases, when tempature is constant
solid
matter that has a definate shape and a definate volume
Surface tension
uneven forces acting on the particles on the surface of a liquid
evaporation
vaporization that occurs only at the surface of a liquid
pressure
amount of force applied per unit of area
viscosity
measurment of a liquids resistence to flow
liquid
matter with definate volume but no definate shape
deposition
change of state of a gas to a solid without going through the liquid state
