2 gas liquid matter solid state of matter cooling heating melting freezing solid condensation evaporation liquid gas mixture strainer/sieve States of Matter a state of matter that takes both the shape and volume of its container a state of matter that has a definite volume but takes the shape of its container anything that has mass and takes up space attributes that can be observed, measured, or changed without turning into a new a state of matter that has a definite shape and volume a form that matter can take such as solid, liquid, or gas the measure of how hot or cold something is Heating & Cooling taking heat energy away from a adding heat energy to a the amount of heat in matter changing from a solid to a liquid state by adding heat energy changing from a liquid to a solid state by taking heat energy away a state of matter that has a definite shape and volume changing from a gas to a liquid changing from a liquid to a gas a state of matter that has a definite volume but takes the shape of its container a state of matter that takes both the shape and volume of its container Mixtures a combination of two or more materials that can be separated a tool used to separate s by their particle size a specific kind of matter energy force friction gravity magnetism mechanical energy motion position pull push weight work energy light energy rays source friction heat/thermal energy Mechanical Energy ability to cause movement or change a push or a pull a force caused by objects rubbing together that makes them slow down or stop a force that pulls objects toward each other the pulling force between an object and a magnet energy of objects in motion the movement of something from one place to another an object s location; where it is a force that moves an object closer to another object a force that moves an object away from another object a measure of the force of gravity on an object what is done when a force is used to move an object over a distance Light Energy ability to cause movement or change energy that you can see straight lines of light where something comes from or begins Thermal Energy the rubbing of one object or surface against another the energy of moving particles
