B) The water molecules remain together. The salt molecules break apart.
Step-by-step explanation:
When the salt is being place upon the water, the sodium in salt becomes attracted to the water molecules. Both H20(water) & NaCI (salt) start to become drawn, during this reaction. This causes water to remain together, while the salt is broken apart and dissolves. Hope this helps!
The northern hemisphere is warmer in the summer than the winter because the northern hemisphere are pointing toward the sun. Because of this the rays hit us more directly making is hotter. So during the winter when the northern hemisphere is not pointing toward us, it makes is colder. It also depends on the tilt of the axis. When it is more direct it makes the temperature hotter.

Answer:
Normal force, gravity and Friction.
Explanation:
The forces acting on the book are normal formal force which act or exerts by the table on the book while on the other hand, gravity is a force that acts in the downward direction. Friction is the force that acts against the motion of the book and is responsible for lowering speed of the book that is sliding on the surface of the table. If the friction is low between the book and table then the book moves easily on the surface.
In short, air pollution is foul air injurious to health. Air Pollution is anything that goes into the air that is harmful.Most air pollution is man-made. The largest contributor to airpollution is the burning of fossil fuels such as gas and coal. Someof the most common forms of air pollution are: Particulate matterNitrogen oxide (and other oxides of nitrogen) Sulfur oxide AcidRain VOC's (volatile organic compounds) Air pollution can also besaid as the accumulation in the atmosphere of substances that insufficient concentrations, endanger human health or produce othermeasured effects on living matter and other materials. Among themajor sources of pollution are power and heat generation, theburning of solid wastes, industrial processes, and, especially,transportation.
