Phase diagrams, triple point, critical state of the substance.

Learning objective(s) that this lesson is contributing to and assessment criteria

ü  to define relative humidity using a hygrometer and a psychrometer;

Lesson objectives

1)      compare the phase diagrams

2)      define the critical point for different substances

3)      analyze the critical state of the substance

4)      give the definition of the triple point

Success criteria

1) the selection of essential features of physical processes: melting and solidification;

2) comparison of physical processes, the ability to draw conclusions and conclusions on the basis of comparison;

2)            STARTER – What do you know?

If substances at the same temperature have the same kinetic energy, why are they all not liquids, solids, or gases?

3)      Teacher: Transitions of matter from one state of aggregation to another play an important role in nature and in technology. For example, turning water into steam, we can then use it in steam turbines in power plants. By melting metals in factories, we get the opportunity to make various alloys of them: steel, cast iron, brass.

To understand these processes, you need to know what happens to a substance when its aggregative state changes.

Consider the processes of melting and crystallization on the example of ice.

Group work

Students will work in the group for define these quantities and phenomena:

1^st Group: Phase Diagrams

2^nd Group: Triple point

3^rd Group: Critical state of the substance

Descriptors:

-Scientifically based theory given on the paper;

- 2 or more figures illustrate the process

- Given examples for each process which described by group

- All members of the group are participated

Each group show theirs posters

While one group presenting their work, another groups should the assess them using by Descriptors

Teacher explanation

Now, after the students discuss about the their posters, teacher will explain and summarize the topic for this lesson
