| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Chemical Property | arrow_right_alt | the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances. |
Liquid | arrow_right_alt | are the states (solid, liquid, gas) in which matter exists, depending on the behavior of atoms and molecules, which is determined by the amount of thermal energy |
Solid | arrow_right_alt | material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. |
Chemistry | arrow_right_alt | a state of matter characterized by particles arranged such that their shape and volume are relatively stable. |
Physical Property | arrow_right_alt | The particles in a _____ are free to flow, so while a _____ has a definite volume, it does not have a definite shape. ______ consist of atoms or molecules that are connected by intermolecular bonds. |
Matter | arrow_right_alt | A _____ is defined as a state of matter consisting of particles that have neither a defined volume nor defined shape. |
Phases of Matter | arrow_right_alt | a state of matter where the gas phase is energized until atomic electrons are no longer associated with any particular atomic nucleus. |
Gas | arrow_right_alt | a property (as color, hardness, boiling point) of matter NOT involving in its manifestation a chemical change. |
Plasma | arrow_right_alt | a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed. |
In a Physical Change, the makeup of matter is changed.
Changing the size and shapes of pieces or wood would be a chemical change.
When ice melts, a chemical change occurs.
