Task P1
Identify if a substance is an element, mixture or compound from its name and from knowledge of common substances.

AssignmentNo2–“How Physical Properties of Substances
Determine Their Uses”
Task P2
learners could investigate, for example, the physical properties of substances related to an industry (e.g. construction) or a use (e.g. a mobile phone).
Learners could carry out simple comparisons of datafor thermal or electrical conductivity, melting point or boiling point and solubilities.
They could identify trendsin the data and make predictions for chemicals with similar physical properties.
Learners could also be giventhe boiling points of different chemicals and predict their state at room temperature and pressure, e.g. theseparate fractions obtained from the fractional distillation of crude oil.
Learners would haveto relate the uses of the chemicals to their physical properties. At least three chemicals should be studied. Thetutor will have to select the substances carefully so that the unit is delivered efficiently in terms of time. The examples should be straightforward.
Task M2
To achieve M2, learners would have to explain the uses of the chemicals in terms of their physical properties.

Task P4
learners should investigate the different chemical properties of the group 1 and 7 elements, such as how they react with water and air and place the elements in their order of reactivity within the groups.
For group 1 elements this could also include a consideration of how they are stored and that they form alkaline compounds when they react with water.
For group 7 elements their ability to form acidic compounds when they react with water.
Task M4
Complete the above requirement.
Explain the stability of the compounds in groups 1 & 7 compared to their elements (reference to noble gas structure).
Find out about the uses of group 1 and 7 compounds.
