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
