Science chap 6 8th Flashcards
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
