Matter and Mass
A substance that is made up of particles (atoms), that takes up a physical space.
What is Matter?
Both Elements and Compounds are considered this in Chemistry.
What is a Pure Substance?
What is a Mixture?
The process when a scientist heats a mixture and it reaches its boiling point. The liquid leaves and the solids are left behind.
What is Evaporation?
This change occurs when the form or shape of the object is changed.
What is a Physical Change?
The quantity of matter in a physical body.
What is mass?
This is made up of 1 Capital Letter. Sometimes, it is 1 capital letter and 1 lowercase letter too.
What is an Element?
This word indicates when a mixture is present.
What is Aqueous (aq)?
These two separation methods are used for Heterogeneous Mixtures.
What is Filtration and Decantation (Funneling)?
This change occurs over a long period of time, and doesn't change the shape, but the properties of it.
What is a Chemical Change?
What is the difference between Mass and Weight?
Weight changes whether you are on the moon or in school.
Mass DOES NOT change wherever you are!
These are made up of 2 or more Capital letters.
What is a Compound?
Mixtures are classified into these 2 different types.
What is Homogeneous and Heterogenous?
The Heterogenous separation process where liquids pass through, but solids are left behind.
Examples include orange juice with pulp and a swimming pool.
What is Filtration?
A person cutting tomatoes and lettuce for a salad is performing what kind of change?
What is a Physical Change?
The unit that represents Mass in an equation.
What are Newtons (N)?
Compounds can only be separated through these methods.
What is a Chemical Method?
This Mixture does NOT mix through evenly. Both individual substances can be seen in it.
Example: Sand and Water
What is a Heterogeneous Mixture?
The process where a filter paper is required to absorb the liquid and lets the ink travel up. It will even change colors to show what solute is left behind.
What is Chromotography?
This forms when an object goes through a Chemical Change.
What is a New Substance?
The Mass of a Tow-Truck is 4,000 N in New Jersey. The Mass of the exact same truck on Mars is?
What are 4,000 N?
MgS is an example of this Pure Substance.
What is a Compound?
This Mixture has samples that all share the same composition or structure.
What is a Homogeneous Mixture?
When a liquid is heated up, but instead of letting the gas (steam) escape at its highest boiling point, we collect it.
What is Distillation?
An example of a chemical change is?
What is rust forming a nail?
