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.

I took the test and i got it correct I did not know what it was than guessed and got it right.
Answer: The definition of a melting pot is a place where different people or different cultures all come together and begin to merge and mix.
