Definitions
The smallest particle found in matter.
What is an atom?
The particles are attracted to each other, they vibrate but do not move past one another, and will retain its shape.
What is a solid?
When adding or removing heat from a solid, liquid, or gas you....
A combination of different types of matter that can usually be separated back into its original parts.
What is a mixture?
Matter cannot be created or destroyed.
What is the conservation of matter?
Anything that has mass and takes up space.
What is matter?
The particles are loosely attracted to each other, they move freely and past one another, and will take the shape of the object or surface it touches.
What is a liquid?
The process of going from a liquid to a solid.
What is freezing?
The result of two or more types of matter interacting to form a new type of matter.
What is a chemical change?
True or false: the total amount of matter you start with, will remain the same to the end.
True
The different physical forms of matter.
What are the states of matter?
The particles are barely attracted to each other, they vibrate and move past one another, and do not have a definite shape.
What is a gas?
The process of going from a solid to a liquid.
What is melting?
A change that occurs when matter changes form but no new types of matter is formed.
What is a physical change?
True or false: you do not change format all in a reaction.
False
A substance made up of a single type of atom.
What is an element?
Speed up and transfer energy to fast moving molecules that slow down.
What are slow moving particles?
The process of going from a liquid to a gas.
What is evaporation?
A reaction that needs heat in order to proceed.
What is an exothermic reaction?
As energy increases the movement of the particles will _____________ and the temperature will _______________.
As energy increases the movement of the particles will increase and the temperature will increase.
A branch of science that deals with the properties, composition, and structure of elements and compounds, how they change, and the energy release or absorbed when they change.
What is Chemistry?
Bump into slow moving molecules and transfer energy.
What are fast moving molecules?
The process of going from a gas to a liquid.
What is condensation?
A reaction that does not need heat to proceed.
What is an endothermic reaction?
As energy decreases the movement of the particles will _____________ and the temperature will _______________.
As energy decreases the movement of the particles will decrease and the temperature will decrease.
