The Classification of Matter
Define Matter
What is anything that has mass and occupies space?
These are two major categories of energy.
What is Kinetic and Potential?
Three states of matter that occur commonly on Earth.
What solid, liquid, and gas?
Alters the composition of matter by rearranging its particles.
What is chemical changes?
List three physical properties of matter not mentioned in the chapter.
Matter is classified as two different things.
What is pure substances and mixtures?
Two fundamental quantities in the universe.
What is matter and energy?
Occur as energy is added to or removed from matter
What is the changes of state?
The ability to do work.
What is energy?
Describe two kinds of pure substances.
What is an element and compound?
The fundamental particles of elements.
What is atom?
The study of movement and transformation of energy.
What is thermodynamics?
This theory states that matter consists of tiny particles in constant motion.
What is the Kinetic molecular theory?
Consists of two or more materials in distinct regions, called phases.
What is heterogeneous mixture?
State the second law of thermodynamics.
What is the entropy of an isolated system can never decrease?
Used to represent the composition of compunds.
What is Chemical Formula?
Usually is called heat and naturally flows between two points at different temperatures.
What is Thermal Energy?
Causes the state of matter will change from a gas to a liquid and then to a solid.
What is energy being removed from a substances?
A result of net transfer of thermal energy into a system.
What is endothermic process?
Compare compounds and elements.
What is an element consists of only one element while a compound consist of two or more elements?
Matter that can be observed without altering the material's chemical composition.
What is Physical Properties.
What is the Exothermic Process?
The temperature of the substance will increase or the state of matter will change from a solid to a liquid and then to a gas due to_.
The change from a solid to a gas.
What is sublimation?
Identify the elements and the number of atoms of each element.
