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.

<span>The sun's energy is absorbed by the top layer of the ocean water. The water molecules spread apart, become less dense, and cause movement of water. The energy from warmer water transfers to cooler water. Note: Satellite imagery allows you to see this process. Combined with wind currents, water of different densities that is mixing can be seen on the ocean's surface in the form of ripples or swirls.

Answer:
Option c
Explanation:
Stage 3 or night terror which occurs when the transition of the stage of sleep is from third to fourth and is what happened in the child in the given question.
The occurrence of night terror is after ninety minutes (approx) of the sleep of the child and is in transition phase from third to fourth of the Non REM sleep.
Night terrors can result in severe panic state, distress, followed by a sense of helplessness where the child is usually not able to remember the cause of being frightened.
