Atoms
What is an Atom?
A physical change from one state of matter to another that does not alter the chemical makeup.
What is a physical change?
A group of molecules that are mixed up in even distributions
Example: Lemonade, Salt Water
What is a solution?
Particles touch each other and are packed loosely together; has definite volume but NOT definite shape – take the shape of container
What is a Liquid?
Color, Size, Texture, Shape, Volume, Mass, Temperature, Density are all examples of
What is Physical Properties?
Anything that takes up spaces and has mass
What is matter?
Change of state from a solid to a liquid with the addition of energy
What is Melting?
The ability of one substance to dissolve in another substance.
What is solubility?
The particles have a lot of thermal energy and are in constant motion; has NO definite volume or shape – take the shape of container when closed; spread out indefinitely when container is not closed; low density
What is Gas?
The temperature that a liquid changes to a solid
What is Freezing Point?
A pure substance that cannot be broken down into any other substances; made up of only one type of atom
What is an Element?
The change of a substance from a liquid to a gas
What is Evaporation?
Salt, Sugar, Kool-Aid Powder, Hot Chocolate Powder are all examples of this part of a solution.
What is a Solute?
Electrically charged gas
What is Plasma?
The temperature at which a substance changes from a solid to a liquid
What is the Melting Point?
Created when two or more atoms join together
Examples
two or more atoms of the same element (like Hydrogen gas = 2 atoms of Hydrogen)
two or more atoms of different elements joining together (like water = 2 atoms of Hydrogen and 1 atom of Oxygen)
What is a Molecule?
The change of state from a gas to a liquid
What is Condensation?
Water, milk, coffee are all examples of this part of a solution
What is a Solvent?
Particles are closely packed together and vibrate in place; has definite shape and volume
What is a Solid?
The temperature at which a substance changes from a liquid to a gas
What is the boiling point?
The amount of space an object takes up
What is Volume?
The process in which a solid changes directly into a gas
What is Sublimation?
Trail mix, Chicken Noodle Soup, Salad, Pizza are all examples of
What is a Heterogeneous Mixture?
As the movement of water molecules begin to slow down, they go into a phase where they are no longer able to easily move past each other. The water is passing through a phase change and will most likely …
What is a Turn into a solid?
How much mass is present in a given space.
What is Density?
