Chemistry Flashcards
Definitions! What is Matter?
Matter is anything that takes up space.
Definitions! What is Physical Property?
Physical Property is a property of matter not involving in its manifestation (chemical change)
Definitions! What is Density?
Density is the amount of mass in a substance per unit volume.
Definitions! What is Physical Change?
Physical Change is when a substance changes in form, but not in chemical composition.
Definitions! What is Mass?
Mass is the amount of matter or substance that makes up an object.
Definitions! What is Chemical Property?
Chemical Property is a property of a substance relating to its chemical reactivity.
Definitions! What is Chemical Change?
Chemical Change is what causes one or more new substances to be formed.
Definitions! What is Volume?
Volume is the amount of space taken up by a substance.
Definitions! What is Model?
Model is a physical, mathematical or conceptual representation of a system of ideas.
Definitions! What is Theory?
Theory is a group of linked ideas intended to explain something.
Definitions! What is KMT of Matter?
KMT of Matter is the rules that
- All matter is made of very small particles, called atoms or molecules
- There is empty space between particles
- Particles are constantly moving
Definitions! What is Electrons?
Electrons are located outside the nucleus it is a subatomic particle with a negative charge.
Definitions! What is Neutrons?
Neutrons are located in the nucleus it is a subatomic particle with a neutral charge.
Definitions! What is Nucleus?
Nucleus is the central core of an atom, that contains protons + neutrons.
Definitions! What is Atom?
Atom is the basic unit of a chemical element and the basic building block in chemistry.
Definitions! What is Protons?
Protons are located in the nucleus it is a subatomic particle with a positive charge.
What are some ways to describe matter?
Matter can be described by its physical properties.
Matter can be described by its chemical properties.
Matter can be described based on physical and chemical changes.
Matter can be classified based on how it responds to physical and chemical changes.
How does matter affect your life?
Everything—including you—is made up of chemicals.
Chemicals in your daily life have characteristics that make them useful, hazardous, or both.
Handling chemicals and equipment safely is important at school and at work.
How can we describe and explain the states of matter?
Matter can be solid, liquid, or gas.
Matter is made of particles in constant motion.
Changes in state result from changes in particle motion.
The kinetic molecular theory explains physical changes and properties.
How can we investigate and explain the composition of atoms?
Dalton developed an early atomic theory.
Many scientists contributed to the further development of atomic theory.
An atom is made up of electrons, neutrons, and protons.
Atomic theory continues to develop.
Matter —> Pure Substance —> _____ + _____ —> Composed of ____ –>
That contain ____ + ____ + ____!
- Elements + Compound
- Composed of Atoms
- That Contain Protons + Neutrons + Electrons
Different Transformation of States
Melting, Evaporation, Condensation, Solidification, Sublimation & Deposition
Melting = Solid to Liquid Evaporation = Liquid to Gas Condensation = Gas to Liquid Solidification = Liquid to Solid Sublimation = Solid to Gas Deposition = Gas to Solid
What are the 3 states of matter?
Solid, Liquid & Gas
What are 4 main statements from the KMT?
- Constant Movement
- Have Negligable Volume
- Random Movement
- Elastic Collisions
