What is a homogeneous mix?
A mixture where the components that make up the mixture are uniformly distributed throughout the mixture.
What is a melting point?
The temperature when melting happens
What is matter?

Describe the particles/particle motion of a solid.
It has a definite shape and volume, and particles vibrate in place.
What is a compound?

What is an example of a homogeneous mix?
Air, Water
What is the change from liquid to solid?

What is liquid
What is an element?
An element is a substance composed of the same type of atoms
What two categories can pure substances be?
Elements and Compounds
Can heterogeneous mixtures be separated physically?
Yes, the components are not mixed chemically
What is the change from liquid to gas?

Which state do molecules move extremely fast by bouncing off of each other?
What is a molecule?
Two or more atoms chemically bonded together. They can be the same element or different elements.
What is an example of a pure substance?
Gold, water, table salt
Can homogeneous mixtures be separated physically?
No, because you cant identify the individual components
What is it called when a solid turns into gas?
Sublimation
