States of Matter
States of matter - Chapter 2 - Section 1, 2, 3 6th Grade
anything that has mass and takes up space
study of properties of matter and how matter changes
A characteristic of a pure substance that can be observed without changing it into another substance
ability of a substance to change into different substances
basic particle that makes up an element
force of gravity on an object
measurement of how much matter an object contains
the amount of space an object takes up
length x width x height
common unit of measuring volume of solids
the amount of matter in a given space
mass / volume
matter changes its appearance but does not change into a different substance
produces new substances with different properties from those of the original substance
law of conservation of mass
matter is not created or destroyed in any chemical or physical reaction
most common form of energy released or absorbed when matter changes
change in which energy is taken or absorbed
change in which energy is released, or given off
particles are packed closely together
has fixed, closely packed arrangement of particles which results in a definite shape and volume
Has a definite volume but no shape of its own
takes the shape of its container
a substance that flows
does not have a definite shape nor a definite volume
changing states from a solid to a liquid
specific temperature at which a substance melts
change of state from a liquid to a solid
matter that exists in the gas state but is generally a liquid or solid at room temperature
change in state from a liquid to a gas
vaporization on a liquid's surface
vaporization throughout a liquid
certain temperature that causes a substance to boil
particles in a gas lose enough thermal energy to form a liquid
surface articles of a solid gain enough energy to become a gas and do not pass through the liquid state
the average kinetic energy of the individual particles
the total kinetic energy of all the particles in a substance.
the movement of thermal energy from a substance at a higher temperature to one at a lower temperature
common unit for measuring liquid volume
a fluid's resistance to flow
Fourth state of a matter which occurs at extremely high temperatures. Plasma is found in stars, lightning and neon lights.
a solid in which the atoms are arranged in a repeating, three-dimensional patterns.
solids made up of crystals with repeating three-dimensional patterns.
Solids in which the particles are arranged randomly without forming crystal structures.
the uneven forces acting on the particles on the surface of a liquid
particles in a solid can't move out of their fixed position but they vibrate in a fixed position.
the amount of heat required to raise the temperature of 1g of a substance 1 degree Celsius
the upward force that keeps an object immersed in or floating on a fluid
the buoyant force on an object is equal to the weight of the fluid displaced by the object
