Solubility is defined as the amount of a substance that can dissolve in a given amount of solvent. If enough substance is dissolved then the solution is defined as saturated, however, if more of the substance is able to be dissolved then it is considered an unsaturated solution. Temperature affects solubility in different ways, for gases dissolved in water it will decrease with an increase in temperature, in other words, cold water will dissolve more gas than hot water can. Polarity also affects solubility polar molecules are able to dissolve more easily in polar solutions and nonpolar molecules dissolve more readily in nonpolar solutions. As such, the answer to this question is D, the pressure above the solution does not affect solubility. The reason for this is that with a change in pressure there is litter to no change in solubility for solids or liquids, however, gasses as being the exception to most rules, their solubility increases as pressure increases.
Cause (a substance) to be deposited in solid form from a solution.
Answer:
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Hope this is what you mean be hot spot!
I hope this helps you!
Have a great day
During the day or in spring and summer, plants take up more carbon dioxide through photosynthesis than they release through respiration , and so concentrations of carbon dioxide in the air decrease. Then at night or during autumn and winter, plants reduce or even stop photosynthesising, releasing carbon dioxide back into the air. This is often called the natural carbon cycle.
