Air pressure decreases with altitude. The combined weight of air molecules at increasing altitude decreases. Air pressure is greatest at the Earth's surface, because the surface air molecules bear the combined weight of all the air molecules above.Know More
As altitude increases, individual air molecules can occupy a greater volume of the atmosphere. Because air molecules can achieve increasing distances from one another with increasing altitudes, the air can be described as being thinner, or less dense.
For example, aircraft flying at higher altitudes can face control issues because the air becomes increasingly rarefied. The air molecules can reach such a low density that aircraft control surfaces, such as the wings, ailerons and rudder, can become ineffective.Learn more about Particle Physics
To lower blood pressure, increase daily intake of fresh fruits and vegetables, whole grains, legumes and low-fat dairy, according to Mayo Clinic. It is important to avoid excessive sugar, caffeine, sodium and alcohol. Eating foods rich in potassium is thought to mitigate damage caused by sodium.Full Answer >
Entropy means an increase of disorder or randomness in natural systems, and negative entropy means an increase of orderliness or organization. Negative entropy is also known as negentropy. Individual systems can experience negative entropy, but overall, natural processes in the universe trend toward entropy,Full Answer >
Particle theory, also referred to as the kinetic theory of matter, is a theory in science that describes all forms of matter as being composed of tiny particles that are always in a constant state of motion. The theory also states that the degree to which these particles move around depends on the amount of energy that is present in the matter and what the nature of the relationship is between the various particles.Full Answer >
An electron jump from an outermost energy level to the innermost or ground level would emit the highest frequency photon. A greater the drop in energy levels results in a higher frequency of the emitted photon.Full Answer >
