Slide 1 - Slide

Convertion between units
You must be able to convert well
according to the diagrams below.

Try to think logically if
you just don't remember.

Slide 3 - Drag question

Density

Slide 4 - Slide

The amount of a substance can be expressed with volume (the dimensions, how much space does the substance take up) and with mass (how heavy is the substance).
This amount of mass per unit volume (e.g. g/ml or g/m³ or kg/dm³) is called the density of a substance.

Slide 5 - Slide

How do you calculate the mass?
m = ...
A
V / ρ
B
ρ / V
C
ρ · V

Slide 6 - Quiz

TOA-Tim has filled a balloon with 4.50 liters of chlorine gas. The density of chlorine gas is 3.21 g/L. What is the mass of the chlorine gas?
A
4,50 grams
B
0,71 grams
C
1,40 grams
D
14,4 grams

Slide 7 - Quiz

The volume of a stone of 18 grams is determined using the immersion method.
Calculate the density of the stone.
A
0,5 g/mL
B
2 g/mL
C
9 g/mL
D
18 g/mL

Slide 8 - Quiz

Calculate the density in g/mL
Write your answer to 1 decimal place and don't forget to type the unit.

Slide 9 - Open question

The gold medal (right) has a volume of 20.0 cm³. The density of gold is 19.3 kg/dm³. Calculate the mass in grams.
Write your answer to 1 decimal place and don't forget to type the unit.

Slide 13 - Drag question

When particles start moving faster,
A
the particles move further apart
B
the particles move closer together
C
the particles will stick togethe
D
some particles fall apart

Slide 14 - Quiz

According to the particle model, what happens to the molecules during evaporation?
A
they start moving more slowly
B
they let each other go
C
they get bigger
D
they start to vibrate in place

Slide 15 - Quiz

Gases always have a much lower density than liquids.
You can explain this using the particle model.

Which statement is correct?
A
The gas molecules are enormously expanded and therefore take up a much larger space.
B
Gas molecules are much lighter than liquid molecules.
C
The volume of a gas is much larger than that of a liquid.
D
In the gas phase the molecules are much further apart than in the liquid phase.

Slide 16 - Quiz

Drag the texts to the correct or incorrect boxes.
Correct
Incorrect
Molecules exist in all three phases: solid, liquid and gaseous phase.
In the solid phase, molecules vibrate in place.
During a separation, the molecules change.
During a separation method you sort the substances in the mixture.
When two substances dissolve, a new substance is created, so this is a chemical reaction.
During a phase transition, the velocity of the molecules increases.

Slide 17 - Drag question
