Matter

Question 1

How is the quantity of matter described and why?

Answer 1

By mass, because mass isn’t affected by environmental factors and others that can cause it to become unreliable.

Question 2

Five main stages of matter

Answer 2

Solid
Liquid
Gas
Plasma
Bose-Einstein condensate (extremely cold)

Question 3

What is matter made of

Answer 3

Molecules ( smallest part of a substance and still holds properties and composition of that substance.)

Question 4

Properties of solid matter

Answer 4

occupies a Definite space

has Definite shape

Question 5

Properties of liquid matter

Answer 5

Occupies definite space
has no definite shape
Conforms to the shape of space it occupies

Question 6

Properties of gas

Answer 6

Occupies any and fills all space available

no definite shape

Question 7

Changes it can go under

Answer 7

Physical changes (appearance is changed but no new substance is made)

Chemical Change (A new substance is produced)

Question 8

Temperate change

Answer 8

RISE IN TEMP
solid + heat = liquid
liquid + heat = gas

FALL IN TEMP
Vapor(gas) - heat = liquid (CONDESATION)
Liquid - heat = solid

Question 9

sublimation

Answer 9

solid directly turns into gas

Question 10

deposition

Answer 10

gas directly into solid

Question 11

Pure Substance

Answer 11

has definite or constant composition

can either be an element or compound

Question 12

Mixture

Answer 12

physical combinations of pure substances
separated by physical means
can be heterogeneous (varies) or homogeneous (relatively the same)

Question 13

element

Answer 13

composed of atoms (smallest part of an element) that contain the same properties of that element

Question 14

Compound

Answer 14

made up of two or more elements; separated by chemical changes
