Whenever energy is converted from one form to another in a physical or chemical change, no energy is created nor destroyed; also called the Law of Conservation of Energy (4 words)
Number of protons in the nucleus of an atom (2 words)
A double helix DNA molecule wrapped around some proteins
Matter Quality that is highly concentrated, is usually found near the Earth’s surface, and has great potential for use as a resource
Combinations of two or more different elements held together in fixed proportions
Atom or group of atoms with one or more positive (+) or negative (-) electrical charges
A possible explanation of what scientists observe in nature or in the results of their experiments (2 words)
Solution that has a pH less than 7; water solution with more hydrogen ions than hydroxide ions
The capacity to do work or transfer heat
Process that occurs when an output of matter, energy, or information is fed back into the system as an input and leads to changes in that system (2 words)
Change of a radioisotope to a different isotope by the emission of radioactivity (2 words)
A combination of 2 or more atoms of the same or different elements held together by forces called chemical bonds
A set of components that function and interact in some regular way
Data, hypotheses, models, theories, and laws that are widely accepted by all or most of the scientists who are considered experts in the field under study (2 words)
From the environment
Two or more forms of a chemical element with the same number of protons but different atomic numbers because of different numbers of neutrons
A measure of the capacity of a type of energy to do useful work (2 words)
Change where there is no change in chemical composition
Feedback loop that causes a system to change in the opposite direction from which it is moving; also called Corrective Feedback Loop
A well-tested and widely accepted scientific hypothesis or a group of related hypotheses (2 words)
Chemical characteristic that helps determine how a substance dissolved in water (a solution) will interact with and affect its environment; based on amount of hydrogen and hydroxid
Feedback loop that causes a system to change further in the same direction
Sum of the number of neutrons and the number of protons in the nucleus of an atom; it gives the approximate mass of that atom (2 words)
Interaction of 2 or more factors or processes so that the combined effect is greater than the sum of their spate effects (2 words)
HintAnswer

Compound that contains at least 2 carbon atoms combined with atoms of 1 or more other elements
To the environment
Anything that has mass and takes up space
Any process that increase or decrease a change to a system
Whenever matter undergoes a physical or chemical change, no atoms are created nor destroyed (5 words)

Nuclear change where the nuclei of certain isotopes with large mass numbers are split apart into lighter nuclei when struck by a neutron (2 words)
Solution that has a pH greater than 7
A measure of acidity
Energy associated with motion
Nuclear change where 2 nuclei of elements with a low mass number are forced together at extremely high temperatures to form a heavier nucleus (2 words)

The point at which a fundamental shift in the behavior of a system occurs (2 words)
The idea that all elements are made up of atoms; the most widely accepted scientific theory in chemistry (2 words)
Primarily scientific data, hypotheses, and models that have not been widely tested and accepted; also called Frontier Science (2 words)
The distance between successive peaks or troughs in the wave
Energy Quality that is so dispersed that it has little capacity to do useful work
The smallest unit of matter into which an element can be divided and still have its characteristic chemical properties
When energy is changed from one form to another, it always goes from a more useful to a less useful form (4 words)
A measure of how useful a form of matter is to humans as a resource, based on its availability and concentration (2 words)
