Answer: the filled in options are(from up to down): decreases; increases; decreases and increases
Explanation:
Ok, let us first full in the gap from the question;
''When a nonvolatile solute is added to a volatile solvent, the solution vapor pressure DECREASES, the boiling point INCREASES, the freezing point DECREASES, and the osmotic pressure across a semipermeable membrane INCREASES.
First, volatility is the tendency of a substance to vaporize.
WHAT IS A NON VOLATILE SOLUTE/SUBSTANCE ?:
A non volatile solute will not produce vapour at the boiling point of a particular solution. It is a solute that has low vapour pressure. This property, that is, a low vapour pressure will cause an increase in the boiling point. An example is glucose.
Non volatile solute, apart from increament in boiling point called boiling point elevation, it also decreases freezing point called freezing point depression.
Also, colligative properties such as osmotic pressure increases.
The correct answer is letter B.
Explanation: The Social Penetration Theory explain the differences in communication and proposes that as much as relationships develop, the interpersonal communication shifts from relatively shallow, to deeper and more intimate levels.
The more people know each other their communication gets better, and they are able to have a deep and intimate connection.
