Ethanol would be better than mercury for an outdoor thermometer in the Arctic because ethanol has a lower freezing point than mercury, making it more reliable in extremely cold temperatures. Additionally, ethanol is less toxic than mercury, which is important for environmental and safety reasons in outdoor settings.
Mercury because butter does not freeze. Butter does not have a freezing point. Butter is a fat that solidifies gradually as it gets colder and does not go through a phase change (freezing) abruptly like mercury or water.Although butter will become as solid as it gets at a temperature closer to that of the freezing point of water than the freezing point of mercury.
It is lower.
boiling point is 629K freezing point is 234K
To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.
Oxygen has a lower point.
Oxygen has a lower freezing point than ethanol. This is because the intermolecular forces in oxygen molecules are weaker than in ethanol molecules, allowing oxygen to freeze at a lower temperature.
Oxygen has a lower freezing point than ethanol because the molecular structure of oxygen is simpler, with weaker intermolecular forces between oxygen molecules compared to the ethanol molecules. This results in oxygen being a gas at room temperature and having a lower freezing point than ethanol, which is a liquid.

The freezing point of ethanol is -114 0C. The boiling point of ethanol is 78,37 0C.
Because whoever told you this is an idiot or lives in an alternative universe.NaCl is a solid at room temperature. Ethanol is a liquid at room temperature. NaCl, as an ionic compound, has a higherfreezing point than a covalently bonded compound such as ethanol.Another possibility is that you didn't understand what was said and left out some words in your question. If you add an equal number of moles of sodium chloride and ethanol to the same amount of water, the sodium chloride solution will have a lower freezing point for several reasons, chief among them that sodium chloride dissociates in water and ethanol doesn't.
Before the use of mercury, alcohol (usually ethanol or dyed spirits) was commonly used in thermometers. Alcohol thermometers were popular because alcohol has a lower freezing point than mercury, making them suitable for a wider range of temperatures.
An ethanol thermometer would be better suited for use in the arctic compared to a mercury thermometer. This is because ethanol has a lower freezing point (-114°C) compared to mercury (-39°C), making it more reliable in extremely cold temperatures. Additionally, ethanol is safer to use as it is non-toxic in case of breakage.
The freezing point of ethanol decreases as the concentration of ethanol increases. Pure ethanol freezes at -114.1 degrees Celsius, while a 40% ethanol solution freezes at around -26 degrees Celsius. This is due to the phenomenon of freezing point depression, where the presence of solute particles in a solvent lowers the freezing point of the solution compared to the pure solvent.
Ethanol's freezing point is -114.1
