________ in solids are held tightly in place by the attraction between the particles.
Thermal Expansion
________: an increase in the size of a substance when the temperature is increased.
Buoyancy
________: the ability of a fluid- a liquid or a gas- to exert an upward force on an object immersed in it.
Boyles law
When ________ is applied to a real life situation, we find that the pressure multiplied by the volume is always equal to a constant if the temperature is constant.
Expansion
________ and contraction occur in most solids, liquids, and gases.
Diffusion
________ occurs in solids and liquids but occurs most rapidly in gases.
Viscosity
________: The resistance to flow by a fluid.
Evaporation
________ is vaporization that occurs at the surface of a liquid and can occur at temperatures below the liquids boiling point.
Pascals principle
According to ________, pressure applied to a fluid is transmitted throughout the fluid.
Charles’s law
________ can be explained using the kinetic theory of matter.
Plasma
________ exists where the temperature is extremely high.
Kinetic Theory
________: an explanation of how particles in matter behave.
buoyant force
If the ________ is equal to the objects weight, the object will float.
Heat of Fusion
________: The amount of energy required to change a substance from the solid phase to the liquid phase at its melting point.
Heat of Vaporization
________: the amount of energy required for the liquid at its boiling point to become a gas.
Solid ice
________ is less dense than liquid water.
Liquids
________ do not have an orderly arrangement of particles.
Hydraulic machines
________ are machines that move heavy loads in accordance with Pascals principle.
Gases
________ do not have a definite volume or shape.
Thermal energy
________ is the total energy of a materials particles, including kinetic- vibrations and movement within and between the particles- and potential- resulting from forces that act within or between particles.
Diffusion
________: the spreading of particles throughout a given volume until they are uniformly distributed.
Bernoullis principle
According to ________, as the velocity of a fluid increases, the pressure exerted by the fluid decreases.
Charless law
According to ________, the volume of a gas increases with increasing temperature, as long as pressure does not change.
Plasma
________: matter consisting of positively and negatively charged particles.
