Intro to Matter
Anything that has mass and takes up space
What is Matter?
Referred to as Solid, Liquid, Gas, Plasma.
What is the four States of Matter?
Freezing point is the temperature at which:
What is a liquid turns into a solid?
The smallest unit of an element that still retains the properties of that element>
What is an atom?
This type of substance has a fixed composition and can either be an element or a compound.
What is a pure substance?
Which of the following is not considered matter? Air; Water; Light; Rock
What is Light?
Gaseous form of a substance that is normally a liquid or solid at room temperature,
What are vapors?
Boiling Point...
What is liquid to gas?
This type of substance is made up of only one kind of atom.
What is an element?
This type of mixture can be separated by physical means, like sorting or filtering.
What is a mixture?
Particles make this up.
What is All Matter?
Increasing pressure typically causes gases to...
What is Condense?
Melting point...
What is a solid to liquid?
When two or more elements are chemically combined, they form this.
What is a compound?
In this mixture, the components are evenly distributed, and you cannot see the different parts.
What is a homogeneous mixture?
According to the Kinetic Molecular Theory, what happens to gas particles as temperature increases?
They speed up and move more energetically
Endothermic Reaction
What is absorbes heat?
The process of a solid changing directly to a gas?
What is Sublimation?
These two elements are combined to form water?
What are hydrogen and oxygen?
In this type of mixture, the different parts are visible, and the components are not evenly mixed?
What is a heterogeneous mixture?
The lowest possible temperature where particles have minimal motion
What is Absolute Zero?
Exothermic reaction.
What is releases heat?
During this process a gas changes to a solid
What is deposition?
This type of change occurs when a substance changes its shape or state but not its identity.
What is a physical change?
A change in color, such as rust forming iron, is a sign of this.
What is a chemical change?
Mass is the measure of...
What is the amount of matter in an object
Density is defined as:
What is Mass divided by volume? D = M/V
Process where a gas changes into a liquid when it cools down.
What is condensation?
Cutting a piece of paper is an example of this kind of change.
What is a physical change?
The formation of bubbles or gas is often a sign of this type of reaction.
What is a chemical reaction?
Volume refers to:
What is the amount of space an object takes up?
This is the density of water in grams per cubic centimeter (g/cm3)
What is 1.0 g/cm3?
Process by which a liquid turns into a gas, often occurring when the liquid is heated.
What is evaporation?
This substance is known as theuniversal solvent, because it can dissolve more substances than any other liquid.
What is water?
When a substance undergoes this type of change, it forms a new substance with different properties.
