100
Anything that has mass and takes up space.
What is Matter
100
Energy of an object that is due to the object's motion.
What is kinetic energy
100
Neutrally charged particle in the nucleus of an atom
What is neutron
100
the color change, odor change, formation of a gas, and formation of a solid
What is changes in properties for a chemical reaction
100
the smallest particle of an element that retains all the properties of that element.
What is atom
200
A physical or chemical reaction, (matter) or mass can neither be destroyed or created.
What is the law of conservation of mass?
200
Energy that an object has because of its position, shape or condition
What is potential energy
200
The sum of protons and neutrons in the nucleus of an atom
What is atomic number
200
the substance or substances that are created by a chemical reaction
What is products
200
the ability to do work
What is energy
300
Homogeneous
What is components of mixture that are evenly distributed and hard to separate and hard to identify.
300
All matter is made up of atoms or groups of atoms and they are constant in motion
What is kinetic theory of matter
300
Sum of Protons and Neutrons in Nucleus of Atom.
What is mass number
300
Substance or substances that are changed by a chemical reaction.
What is reactants
300
Form as large molecules where carbon bonds with other carbon (and other types of atoms) to make complex molecules.
What is carbon chains
400
Heterogeneous
What is components are not evenly distributed, easy to identify and separate.
400
Measure of average kinetic energy of the particles that make up an object (or how hot or cold an object is)
What is temperature
400
The force of attraction that holds atoms or ions together
What is chemical bond
400
Change that alters the form or appearance of a substance but does not create a new substance.
What is physical change
400
When two nuclei join together
What is nuclear fusion
500
A mixture of tiny particles that are intermediate in size.
What is colloids
500
Scientific scale for temp (usually for cryogenic work) (20th Century)
What is Kelvin
500
The smallest unit of a substance that maintains the physical and chemical properties of that substance.
What is molecule
500
The continuous series of nuclear reactions, number of reactions increases exponentially
What is nuclear chain reaction
500
the change of state from a solid to a gas. Ex: dry ice
What is sublimation
