1

Adhesion

Adhesion is when two objects stick together like tape

2

Atom

An atom is a small molecule that can be found in everything

3

Boil

Boiling is turning a liquid into a gas by increasing heat until evaporation

4

Chemical Change

When an object change due to chemicals. For instance, vinegar and baking soda sizzle

5

Chemical Properties

Chemical Properties are the characteristics that tell how two objects with react with one another

6

Chemistry

Chemistry is the study of matter, their properties and how react with one another

7

Cohesion

Cohesion is when particles of a type of matter attract to one another

8

Compound

A compound is a pure substance containing two or more elements united chemically

9

Density

Density is the relation between weight and the amount of space something takes up

10

Element

is when atoms are of the same kind of pure substance

11

Filtering

is when you separate solid from liquid

12

Gas

is a state of matter which takes up the entire space of a container and it has low density

13

Heterogeneous Mixture

is when different substances mix with one another to make a new compound. The appearance is not the same throughout, meaning you can see the different substances within

14

Liquid

A state of matter in which the substance take up the shape of its container

15

What is an example of a liquid?

Sap

16

The two elements hydrogen and oxygen mix together to make what compound?

H2O, also known as water!

17

What are Physical Properties? Give four examples.

The physical properties of an element include its state of matter, density, colour and boiling point.

18

What is a Product?

A product is the substance that is the result of a chemical reaction.

19

Pure Substance

When all the atoms are the same kind

20

Reactant

an element or compound that enters into a chemical reaction

21

Saturation. Give example.

when a solution is not able to hold anymore solute at that temperature. For example, if you are mixing salt into water, you have reached saturation if the salt you add no longer dissolves.

22

Solid

a state of matter where the substance has a set shape and volume

23

Solute

the substance that is dissolved in a solution

24

Solution

a homogeneous mixture where the solute is distributed evenly throughout the solvent

25

Solvent

the substance that does the dissolving in a solution

26

Homogeneous Mixture

A mixture that has the same appearance and form throughout

27

Is milk a homogeneous mixture or heterogeneous?

Homogeneous because milk looks the same throughout

28

Is soda a homogeneous or heterogeneous mixture?

Heterogeneous because you can see the bubbles in the liquid and so the mixture is not the same throughout

29

In salt water, what is the solute?

The salt because it is what is dissolved

30

In salt water, what is the solvent?

The water because it dissolves the salt

31

In salt water, what is the solution?

The salty water, because the solution is the mixture

32

When you mix cocoa powder and hot water/milk, what is the product?

hot chocolate

33

In what state of matter is a popsicle?

Solid

34

What is the boiling point of water?

100℃

What is the term for when two objects stick together?

adhesion

36

Is gas more or less dense than liquid?

less

37

Is solid more or less dense than liquid?

more

38

What is the word for the explosion that happens when you drop a mento in coke?

Chemical Reaction

39
