What Is Matter by Mind Map: What Is Matter

1. Phase Change

1.1. Definition

1.1.1. Phase change takes place when heat is added to or removed from substance

1.1.2. Matter change from one form to another

1.1.3. Matter usually transforms gradually from a solid to a liquid to gas. How ever, a solid can change directly into a gas and a gas can change directly into a solid Sublimation is the change of a solid directly into a gas Deposition is the change of a gas directly to a solid

1.2. There are 4 major phase changes

1.2.1. Freezing Removing heat from a liquid substance can cause the substance to transition from a liquid to a solid Transition from a liquid to a solid is called freezing The temperature at which a liquid freezes to a solid is called freezing point

1.2.2. Melting Adding heat to solid substance to transition from solid to liquid Transition from solid to liquid is called melting The temperature at which solid melts to liquid is called melting point

1.2.3. Condensation Removing heat from a gas can cause substance to transition from a gas to liquid Transition from a gas to liquid is called condensation The temperature at which a gas condenses to a liquid is called condensation point

1.2.4. Evaporation Adding heat to a liquid substance can cause the substance to transition from a liquid to a gas Transition from ilquid to gas is called evaporation The temperature at which a liquid evaporates to a gas is called boiling point

1.3. Heating & Cooling

1.3.1. a phase change takes place because the thermal energy is transferred to or from a substance

1.3.2. Adding thermal energy to a substance is called heating

1.3.3. Removing thermal energy from a substance is called cooling

2. Plasma: 4th State Of Matter

2.1. Most common state of matter in universe, not commonly found on earth

2.2. Most like a gas

2.3. When gas is heated to very high temp, electrons are "torn off" the atoms. Results in mass of positively charged atoms & negatively charged electrons

3. States Of Matter

3.1. Liquid

3.1.1. Matter composed of atoms loosely packed

3.1.2. Atoms can slightly move around due to some space between

3.1.3. Definite volume, do not have definite shape

3.2. Gas

3.2.1. Matter composed of atoms loosely packed together

3.2.2. A lot of space between atoms, constantly moving around

3.2.3. Do not have definite volume or shape

3.3. Solid

3.3.1. Matter composed of atoms, packed tightly together

3.3.2. Has definite shape & volume

4. Definition

4.1. Matter: Anything that takes up space and has mass

4.2. Mass: Amount of stuff in an object or substance

5. Energy Is Not Matter

5.1. Energy does not have mass

5.2. Energy does not have volume

6. Properties Of Matter

6.1. Specific characteristic of matter

6.2. Used to identify the matter that makes up an object or substance

6.3. 2 kinds of properties

6.3.1. Physical Properties Characteristics of matter that can be observed or measured Can change without the substance becoming a different substance Study physical properties using tools or our sense Temperature Is a measure of how hot/ cold an object or substance is Measured in degrees Fahrenheit/ degrees Celsius Temp indicates how much thermal energy an object has. Temp increases the objects thermal energy increases Mass Is a measure of the amount of "stuff" in an object Mas of an object depends on the type of atoms found in the object & how closely the atoms are packed together Is measured in grams (g) Density A measurement that reflects how much mass takes up a certain amount of space ='s the mass of an object divided by its volume Is measured in grams/ milliliters (g/ml) Mass of atoms, the size and how atoms are arranged determine the density of a substance Objects with the same volume but different masses have different densities Some physical properties of matter are qualitative Are observed using your sense, they are descriptive characteristics of matter The most important qualitative properties of matter

6.3.2. Chemical Properties Characteristics of matter that describe the chemical makeup of a substance Describe the ability of a substance to change its identity Study chemical properties through chemical reactions

7. Size & Shape

7.1. Size & shape describe the dimension of an object

7.2. Length, width and height describe the size of an object

7.3. Volume describes how much space an object takes up

7.4. Length, width and height are measured in meters (m)

7.5. Volume is measured in liters (L) or metters3 (m3)

7.6. General 2 or 3 dimensional form of an object is the shape of the object

8. Conductivity

8.1. How well an object/ substance transfers electricity/ heat

8.1.1. Transfers is called conduction

8.2. Objects that conduct electricity/ heat well are called conductors

8.2.1. Objects that do not conduct electricity/ heat well are called insulators

8.3. Thermal conductivity describes how well a substance transfers heat

8.3.1. The higher thermal conductivity of a substance the better it conducts heat

8.4. Electrical resistivity describes how much resists electricity flowing through it.

9. Magnetism

9.1. An invisible force exerted by some types of matter

9.2. Objects that exert magnetism are called magnets

9.2.1. Magnets attract or repel other magnets

9.3. Objects that are attracted to or repelled by magnets, but do not produce magnetism are called magnetic objects

9.4. Most magnets/ material contain iron, nickel or cobalt

10. Solubility

10.1. Describes how well a substance dissolves into another substance to produce a solution

10.2. Dissolve means to become incorporated into another substance.

11. Viscosity

11.1. Is a property of matter that is important to fluids. Fluids can be liquid or gas

12. Boiling Point

12.1. Temperature at which fluid evaporates

13. Melting Point

13.1. Is the temperature at which a solid melts

14. Intensive Vs. Extensive

14.1. Physical properties of matter are intensive or extensive

14.2. Intensive properties of matter never change for a given substance or material

14.3. Extensive properties of matter can vary for a given substance or material.

15. Chemical properties

15.1. Several important chemical properties of matter

15.1.1. Reactivity

15.1.2. Corrosion (oxidation & tarnish)

15.1.3. Toxicity

15.1.4. Flammability

15.1.5. Combustibility

15.1.6. Radioactivity

15.1.7. pH

16. Reactivity

16.1. describes how easily & fast a substance undergoes a chemical reaction

16.2. Substance that easily and quickly reacts with other substance is said to be reactive

16.3. Substance that does not easily or quickly react with substances is said to be inert
