What happens to a glass of water as the average molecular kinetic energy of the water molecules increases?
the water becomes more acidic.
the water becomes warmer.
the water becomes cooler.
the water turns to ice.

The water becomes warmer.

Explanation:

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. The molecules start moving more randomly. It is determined by the equation:

From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if the average molecular kinetic energy increases, the temperature of the water must have increased and thus the water will become warmer.

answer: i would say b.

explanation:

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
