The basic building blocks of matter, Atoms cannot be divided.
The temperature at which liquid becomes a gas.
A property that defines matter and how it interacts with other substances in the world.
To press or squeeze together.
The phase change that occurs when vapor or gas cools and changes to liquid. Heat must be removed from the substance.
The temperature at which a gas becomes a liquid.
A physical property defined by dividing the mass of the substance by the volume.
Substances that can't be separated into simpler substances and still act like the substance.
The temperature at which a liquid becomes a solid.
Phase/state of matter where molecules move very fast, bounce off of each other. Indefinite shape and volume. Occurs after enough heat is added to a liquid.
Phase/state of matter where molecules slide past each other and are not bonded to each other. Indefinite shape and definite volume. Occurs after enough heat is added to a solid to break the bonds. Takes the shape of the container.
A measure of how much matter there is in an object.
Anything that takes up space and has mass.
The smallest part of a substance formed by chemical bonding. Water is and example of a molecule.
The temperature at which a solid becomes a liquid.
A physical condition or state of matter.
The part of an object that can be experienced by using one of the 5 human senses (hear, see, smell, taste or feel)
Phase/state of matter that has more energy than a gas. Plasma is different from a gas because it is made up of groups of positively (nucleus) and negatively charged particles (electrons) instead of atoms.
describes how an object looks, feels or acts.
One state, or phase, of matter that is hard to compress and holds it's shape and has a definite volume. The atoms/molecules are bonded together in a set format where they vibrate in place.
A physical condition or phase of matter
Another word for gas
The amount of space an object occupies.
Where heat is released
Phase change from Liquid to Solid. Liquid loses energy.
Phase change from Solid to Gas. Dry Ice is an example.
Phase change from Gas to Liquid. Water on the bathroom mirror or a ice water glass is an example. Gas loses energy.
Solid to Liquid. Solid gains energy.
Phase change from Gas to a Solid without becoming a liquid. Frost is an example.
Phase change that occurs when a liquid atoms or molecules gain enough energy to change to gas.
Behavior of a substance during a phase change
Either absorbs or releases energy
At super low temperatures (near absolute zero) atoms become super unexcited and super cold and clump together forming a super atom!
In physics, a FORM of ENERGY associated with the movement of atoms and molecules in any material. The higher the temperature of a material, the faster the atoms are moving, and hence the greater the amount of energy present as heat.
