Matter Basics
Define Matter
What is anything that has mass and takes up space
State of matter that takes the shape of its container but has a definite volume?
What is a liquid?
Mass is this type of physical property.
What is extensive?
This method of separation involves pouring off a less dense liquid.
What is decanting?
The first step of the scientific method.
What is observation?
Give an example of an intensive property.
What is density, color, boiling point, melting point, malleability or ductility?
What is they vibrate in place but don't move freely.
An example of an intensive property is this.
What is density, color, malleability, ductility, etc?
This method separates a dissolved solid (typically a salt) from a liquid.
What is evaporation?
A hypothesis is known as this.
What is a solid?
How are particles spaced in solids, liquids, and gases?
What is solids are tightly packed, liquids are close but able to slide past each other, and gases are far apart.
Rusting iron is an example of this type of change.
What is a chemical change?
This method separates liquids based on boiling points.
What is distillation?
After forming a hypothesis, this is the next step of the scientific method.
What is conducting an experiment?
H2O
State of matter with particles that are far apart and move freely.
What is a gas?
Boiling water is an example of this type of change.
What is a physical change?
This method separates by using paper and a solvent.
What is chromatography?
While an observation is information collected, a conclusion is this.
What is a judgement based on results.
Explain the difference between an element and a mixture.
What is a mixture is a physical blend of substances, and elements are the pure substance of one type of matter (can't be broken down)
Particle movement from the solid state to the liquid state to the gas state does this?
What is increase in movement and spread apart?
Density is an intensive property for this reason.
What is density doesn't depend on the amount of matter present?
These methods would be used to separate a mixture of alcohol, water, and sand?
What is filtration and then distillation?
A hypothesis must be testable for this reason.
What is so that it can supported or rejected through experiments.
