<em>"Sedimentary rocks are formed by the pressure over millions of years of organic material, inorganic material, sediment of course , and earth piling up over itself. Metamorphic rock and igneous rock originate either below the surface where plants lived and creatures roamed, or the heat from volcanic activity transformed everything. Sedimentary rock formation is the only geologic activity that permits and allows organic material preservation and hence fossil formation." </em>- <u>Charles Snider, Co-Founder of American Geode (on Quora.com)</u>
In my opinion, the answer is the second option.
Answer:
<h2>
32°F
/0°C
</h2>
Explanation:
At what temperature does the melting point occur?
32°F
/0°C
(32°F − 32) × 5/9 = 0°C
At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a liquid (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing points are about the same temperature.
Is Melting Point affected by temperature?
Melting point, the temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
The easiest way to answer this question is to first figure out the molar mass of the sugar in question. To do this multiply the number of individual atoms for a given element by its atomic mass. 12 X 12.01 g/mol = 144.12 g/mol C. 22 X 1.008 g/mol = 22.176 g/mol H. 11 X 16.00 g/mol = 176.00 g/mol O.
