153781
Properties of methanol\n1. Methanol is a colourless liquid at room temperature. \n2. Methanol has a slight fruity odour. \n3. The boiling point of methanol is 64.5°C. \n4. Methanol is completely miscible in water. \n5. The density of methanol is less than water. \n6. Methanol is a neutral solution and shows negative results for all acid tests. \n7. Methanol is poisonous and if ingested can cause blindness. \n8. Methanol is very flammable and burns with a pale blue flame. It forms carbon dioxide and water on complete oxidation or combustion. \n9. Methanol reacts with Na to give off hydrogen gas. \n10. Methanol reacts with ethanoic acid to give methyl ethanoate which is an ester.

OK...To answer this, you have to recognize that the free energy change at the boiling point is zero.  So, beginning with DG (D=Delta), you have:\n\nDG=DH-TDS=0\n\nSo, DS=DH/T \n\nwhere T is the boiling point is Kelvin.  If you substitute the values for DH and T, you can calculate the entropy change for the vaporization of trimethylamine.

If you are from the philippines, chances are it's methanol. It's cheap and convenient to use (in terms of burning and handling in lab classes). Just be careful. Avoid inhalation, ingestion, and skin contact. It is known to be highly toxic.

Mercury freezing point: -38.72 degrees C\n\nA mercury thermometer will probably lose accuracy somewhat above the freezing point, because as one approaches the phase\ntransition from liquid to solid, one loses the linear dependence\nof the column length on temperature.\n\n\nAlcohol's freezing point is -117 degrees therefore it doesn't get cold enough to freeze alcohol.\n\nTherefore alcohol is better at low temperatures

Pure dry Ethanol (Ethyl alcohol) boils at 78.5 degrees C.  This is a little higher than the typical 78.3 °C or 78.4 °C reported in many older texts.\n\nIf you are talking about a still, Ethanol forms a constant-boiling mixture, or azeotrope, with water that contains 95% ethanol and 5% water and that boils at 78.15°C

Are you seriously a 4th grader...^\n\nProbably because the liquid may be slightly impure and the only way to get the true boiling point of the liquid is to measure the temperature at the reflux ring.

Methanol, also known as methyl alcohol or wood alcohol, is a chemical compound with chemical formula CH3OH. It is the simplest alcohol, and is a light, volatile, colourless, tasteless, flammable, poisonous liquid with a very faint odor. It is used as an antifreeze, solvent, fuel, and as a denaturant for ethyl alcohol.\n\nMethanol is produced naturally in the anaerobic metabolism of many varieties of bacteria. As a result, there is a small fraction of methanol vapor in the atmosphere. Over the course of several days, atmospheric methanol is oxidized by oxygen by the help of sunlight to carbon dioxide and water.\n\nLarge scale production methods can be found in the sources listed. Small scale production can be achieved through destructive distillation of wood.

Have you heard of boiling and freezing points. Each substance has a boiling and a freezing point there is a different one for each substance. The freezing point of H20 (hydrogen and oxygen) is 32 degrees Fahrenheit and the boiling point is 212 degrees Fahrenheit. Now these temperatures could be different if the water has anything else in it changing the molecular structure. Things like salt, calcium, ect. So in your bottle story....The gas (common air) which has things like helium, carbon and oxygen is on top and your water is on the bottom. This could get confusing but essentially when you shake it up you added other molecules into the water that have a lower or higher freezing point. Same idea as when you have a partially frozen bottle of water and you shake it up and it defrosts. It also has to do with the first law of thermodynamics...Energy can not be created or destroyed just transferred. So some molecules do not have enough energy to bond with one another but when you shake up the bottle it transfers energy allowing them to bond with one another. Hope I didn't confuse you too much.

Like all elements, its physical state depends on temperature and pressure. It is a liquid at room temperature, but can be frozen and evaporated at extreems.\n\nIt freezes at -38.83 °C, -37.89 °F\nIt boils at 356.73 °C, 674.11 °F

Everything has a melting point and a boiling point.  In the case of water, the melting point is 0 C and the boiling point is 100 C.  In argon, as you have pointed out, the melting point is much, much lower, whereas for something like iron, it is 1535 C.  Neither of these temperatures occur normally on Earth's surface.  That's why you don't see puddles of argon lying around on the street, or clouds of iron vapor floating in the air:)

low pressure = lower boiling point = lower dew point

The boiling point series for short alcohols is dominated by hydrogen bonding.  That's where the H on the hydroxyl group (OH)  on one molecule is attracted to the O on a nearby molecule.\nEven tough "normal alcohol" (I imagine you mean n-butanol from the context of your question) is just as heavy, it will have a higher boiling point because its structure makes hydrogen bonding easier.  It is basically alike to a bunch of strings with the magnets on their ends with nothing to impede the other strings from glomming on.\nTert-butanol, on the other hand, is like a bunch of knotted strings with magnets at the base of the knot.  The hydroxyl group on these molecules are not all that available for their neighboring molecules to find and be attracted to.  This is called "steric hinderance" and is more a physical and spatial consideration than a chemical phenomenon.

Right off the bat without looking up anything, I would say CH4 has the lowest boiling point.  Why?  Well, it is the least complex molecule of them all.  Additionally, it is symmetric, therefore non polar.  Since it is the smallest and least complex, it really doesn't have a dipole-dipole interaction such as the other larger molecules, requiring either a lot more pressure to cause condensation or a removal of a lot of heat to really bring it to a low temperature.  Furthermore, there isn't any entanglements when two or more molecules collide, which the larger hydrocarbons are prone to because they have comparatively longer chains.
