Matter

Question 1

Why do we study matter?

Answer 1

To improve our life style and solve problems.

Question 2

Mass

Answer 2

Measurement of the amount of particles something has.

Question 3

Energy

Answer 3

The ability to do work and cause changes.

Question 4

What does a food chain show?

Answer 4

The energy transferred which decreases a 10% each level.

Question 5

How is matter transformed in a food chain?

Answer 5

Through biogeochemical cycles in which it is reused.

Question 6

Kilocalories

Answer 6

Energy stored as biomass.

Question 7

Metabolism

Answer 7

The way we process matter and the energy we consume. Some energy is transformed into heat.

Question 8

Transformation Mass-Mass

Answer 8

Combustion and boiling.

Question 9

Transformation Mass-Energy

Answer 9

Chemical Reactions

Question 10

Types of energy

Answer 10

Wind energy (Kinetic energy from the wind), Electric Energy (Kinetic energy of electrons) and Nuclear Energy (Potential energy from atoms).

Question 11

States of matter

Answer 11

Liquid, solid, gas, plasma and bose-einstein condensate.

Question 12

Quantum states of matter

Answer 12

Plasma and Bose Einstein condensate.

Question 13

Solid

Answer 13

Definite shape and volume. No space between particles, no kinetic energy, no compressibility and no ability to flow.

Question 14

Liquid

Answer 14

No definite shape, fixed volume, some space between particles, some kinetic energy, compressible under extreme pressure and has the ability to flow.

Question 15

Gas

Answer 15

No definite shape or volume, a lot space between particles as well as movement, compressible and flows.

Question 16

Plasma (Ionized gas)

Answer 16

So much heat that the atom breaks apart and leaves a bunch of nucleus and electrons free.

Question 17

Bose-Einstein (Super atom)

Answer 17

It exists at absolute zero because atoms stop behaving like a particle and behave like waves which causes an atom identity loss.

Question 18

Endothermic changes of matter

Answer 18

Melting, Vaporization and sublimation.

Question 19

Exothermic changes of matter

Answer 19

Freezing, condensation and deposition.

Question 20

Solid to gas

Answer 20

Sublimation

Question 21

Gas to solid

Answer 21

Deposition

Question 22

Solid to liquid

Answer 22

Melting

Question 23

Liquid to solid

Answer 23

freezing

Question 24

Liquid to gas

Answer 24

Evaporization

Question 25

Gas to liquid

Answer 25

Condesation

Question 26

Changes of matter

Answer 26

Matter transformation that does not involve measurement scales.

Question 27

Physical Changes

Answer 27

Molecules are kept intact, they only change their organization.

Question 28

Chemical Changes

Answer 28

Molecules modify their structure.

Question 29

Chemical Properties of matter

Answer 29

Based on how reactive something is.

Question 30

Which are the two kinds of physical properties? |

Answer 30

Intensive and Extensive

Question 31

Intensive properties of matter

Answer 31

Doesn't matter how much mass the object has. Color, Melting and boiling point, density.

Question 32

Extensive properties of matter

Answer 32

Determined by how much mass the object has. Mass, Volume, Length and Shape.

Question 33

What are the properties of matter?

Answer 33

Characteristics that allow us to identify a substance by measurement or scale.

Question 34

Are mass and energy the same?

Answer 34

According to the relativist theory mass and energy are different manifestations of matter.

Question 35

Substance

Answer 35

Something that cannot be physically separated.

Question 36

Compound

Answer 36

A substance that can be chemically decomposed

Question 37

Element

Answer 37

A substance that cannot be chemically decomposed.

Question 38

Mixture

Answer 38

Elements merged together in which there is no bonding whatsoever and can be physically separated.

Question 39

Homogeneous Mixture

Answer 39

Uniform composition.

Question 40

Heterogeneous Mixture

Answer 40

Not uniform.

Question 41

Colloids

Answer 41

Appears to be a homgoeneous mixture but has small particles there.

Question 42

Suspensions

Answer 42

Similar to a colloid but has bigger particles.

Question 43

Mass

Answer 43

Amount of matter.

Question 44

Weight

Answer 44

Amount of matter times the force of gravity.

Question 45

Substance

Answer 45

Particular kind of matter with uniform characteristics.

Question 46

Compounds

Answer 46

Substance made up of two or more elements that can be separated chemically.

Question 47

Compressibility

Answer 47

Measure of the change in volume resulting from external pressure applied to the surface of an object.

Answer 48

A fluids resistance to flow.

Question 49

Miscibility

Answer 49

Two liquids with similar polarities mix.

Question 50

Difusion

Answer 50

Atoms merge together as a result of kinetic energy and the concentration equalizes on a lower concentration.
