States of Matter
Describe the three states of matter
Reference: SW9 Pg 37
Task 1
Everything around us is made of matter. Take pictures of 3 objects around the school- you have only 5 min. Insert these pictures
Task 2
Measure the mass using the electronic balance and calculate the volume. Fill in the table below X
Object name Estimated mass Measured mass Calculated volume (l x b x h)
Small Book
Tissue box
White board duster
All matter has X and occupies X
All matter can be organised into 3 states of matter - X, X and X
Task 3

Task 4
Experiment on properties of the 3 states of matter, see text book. SW9 Pg38.
Perform experiment
Fill in the table X
State of matter Can be weighed Occupy space Fixed shape Fixed volume Can be compressed
Solids
Liquids
Gases
Describe and explain changes in state, linking to heating and cooling
Reference: SW9 Pg 45
Task 5
Find a diagram showing how we can change between the three states of matter and paste it here
Task 6
The table below lists five changes of state. For each change decide whether heating or cooling is needed. Place a tick ( √ )in the correct
column and fill in final column. X
Change of state Heating Cooling Energy taken in or energy released
Solid to liquid
Liquid to gas
Liquid to solid
Gas to liquid
Solid to gas
The boiling point of water is X °C, whereas the melting point of water is X °C.
What is the physical state of water at these temperatures?
45 °C X
125 °C X
-23 °C X
75 °C X
Task 7
Here are the melting and boiling points of some elements. What state are they at 25°C?
Element m.p.(0C) b.p. (0C) State at 250C
Chlorine -101 -34 X
Iodine 114 184 X
Fluorine -220 -188 X
Bromine -7 59 X
