Answer:
How to Formulate an Effective Research Hypothesis
State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
Try to write the hypothesis as an if-then statement. ...
Define the variables.
Explanation:
Answer :
The substance is in the gas phase only in region → 5
The substance is in both the liquid and the solid phase in region → 2
The substance is in only the liquid phase in region → 3
The melting point is the temperature at region → 2
The boiling point is the temperature at region → 4
Explanation :
Six phases of substance:
- Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.
- Freezing : In this process the phase changes from liquid state to solid state at constant temperature.
- Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.
- Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.
- Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.
- Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.
