Problem: Ken is an avid mountain climber. This year he reached the summits of two mountains, mountain A and mountain B. Mountain A is only 5000 ft tall while mountain B is 15000 ft tall. He has also learned a fun fact that water boils faster and at lower temperature at low atmospheric pressure. Given the paragraph above, please answer correctly the following question: Would mountain A summit be considered high altitude or low altitude? Hint: Regions on the Earth's surface (or in its atmosphere) that are high above mean sea level are referred to as high altitude. High altitude is sometimes defined to begin at 2,400 meters (8,000 ft) above sea level.[5][6][7] At high altitude, atmospheric pressure is lower than that at sea level. This is due to two competing physical effects: gravity, which causes the air to be as close as possible to the ground; and the heat content of the air, which causes the molecules to bounce off each other and expand.[8]

A: low altitude
Problem: Given the question: Keith was a studying for his chemistry exam. He got interested in solubility of different substances. For that, he conducted five tests, test A, test B, test C, test D, and test E. in test A, he used some liquid solute in a solvent in room temperature. Then in test B, he increased the temperature. In test C, he used some gaseous solute in a solvent in room temperature. But in test D, he increased the temperature. Finally, in test E he replaced the solvents in each of the earlier tests with water. Given the paragraph above, please answer correctly the following question: In case B would the solute be less or more soluble than case A? Hint: As you can see in Figure above , solid and liquid solutes generally become more soluble as the temperature increases. This is true for solvents other than water as well. This effect varies quite a bit by substance. For example, the solubility of KNO 3 has a very strong temperature dependence (its solubility curve has a large slope), whereas the solubility of NaCl is minimally influenced by temperature (its solubility curve is nearly flat). For gaseous solutes, solubility decreases at higher temperatures. We will look more at this effect later in the lesson.

input question: Rob is learning about ionization. He looks at a specific group of elements from top to bottom to figure out thier ionization energy. Given the paragraph above, please answer correctly the following question: Which element will have a higher shielding effect, the top element or the bottom element? Hint: The ionization energies of the representative elements generally decrease from top to bottom within a group. This trend is explained by the increase in size of the atoms within a group. The valence electron that is being removed is further from the nucleus in the case of a larger atom. The attractive force between the valence electron and the nucleus weakens as the distance between them increases and as the shielding effect increases, resulting in a lower ionization energy for the larger atoms within a group. Although the nucl???
output answer: bottom element
In a greenhouse, two new plants have just been planted. Flower D has come from a region of little rainfall. Flower E was taken from an area that sees rain nearly every day of the year. Given the paragraph above, please answer correctly the following question: Which flower would be better at handling not being watered for a long period of time? Hint: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased.

Answer: Flower D
Q: John is a scientist in a large pharmaceutical company. He devices many useful products using his knowledge of chemistry. Today, he has four solutions in front of him, solution A, solution B, solution C, and solution D. Solution A is a buffer, but solution B is not a buffer. Solution C is acidic, but solution D is not acidic. He needs to figure out what each solution does. Given the paragraph above, please answer correctly the following question: Which solution may assist in changes in pH, solution A or solution B? Hint: If only 1.0 mL of 0.10 M hydrochloric acid is added to 1.0 L of pure water the pH drops drastically from 7.0 to 4.0. This is a 1000-fold increase in the acidity of the solution. For many purposes, it is desirable to have a solution which is capable of resisting such large changes in pH when relatively small amounts of acid or base are added to them. Such a solution is called a buffer. A buffer is a solution of a weak acid or a base and its salt. Both components must be present for the system to act as a buffer to resist changes in pH. Commercial buffer solutions, which have a wide variety of pH values, can be obtained.
A: solution B
[Q]: John is a geologist. He was trying to figure out how the Earth's inner core is made. To that end, he compared earth's physical characteristics to available items. First he took a sample of surface rock, which he labeled as item B. Then he took a sphere of constant density, which he labeled as item C. Finally, he labeled the Earth as item A. Given the paragraph above, please answer correctly the following question: Would item C have higher or lower moment of inertia than item A? Hint: Evidence from seismology, heat flow at the surface, and mineral physics is combined with the Earth's mass and moment of inertia to infer models of the Earth's interior its composition, density, temperature, pressure. For example, the Earth's mean specific gravity (5.515) is far higher than the typical specific gravity of rocks at the surface (2.73.3), implying that the deeper material is denser. This is also implied by its low moment of inertia ( 0.33 M R2, compared to 0.4 M R2 for a sphere of constant density). However, some of the density increase is compression under the enormous pressures inside the Earth. The effect of pressure can be calculated using the AdamsWilliamson equation. The conclusion is that pressure alone cannot account for the increase in density. Instead, we know that the Earth's core is composed of an alloy of iron and other minerals.Reconstructions of seismic waves in the deep interior of the Earth show that there are no S-waves in the outer core. This indicates that the outer core is liquid, because liquids cannot support shear. The outer core is liquid, and the motion of this highly conductive fluid generates the Earth's field. Earth's inner core, however, is solid because of the enormous pressure.Reconstruction of seismic reflections in the deep interior indicate some major discontinuities in seismic velocities that demarcate the major zones of the Earth: inner core, outer core, mantle, lithosphere and crust. The mantle itself is divided into the upper mantle, transition zone, lower mantle and D layer. Between the crust and the mantle is the Mohorovicic discontinuity.The seismic model of the Earth does not by itself determine the composition of the layers. For a complete model of the Earth, mineral physics is needed to interpret seismic velocities in terms of composition. The mineral properties are temperature-dependent, so the geotherm must also be determined. This requires physical theory for thermal conduction and convection and the heat contribution of radioactive elements....
