What’s the Freezing Point of Helium? [1]
The chemical elements in group 18 of the periodic table are called noble gases. They’re called noble gases because they’re the most stable as they have the maximum number of valence electrons their outer shell is capable of holding
All of the noble gases conduct electricity and they’re odorless and colorless. Previously, they used to be called inert gases but that term is not technically accurate
One of the six noble gases, Helium, is widely used in the cryogenics processing industry. It has specific properties that make it suitable for cryogenics.
Which Material Has the Lowest Freezing Point? (with picture) [2]
The material with the lowest freezing point is helium. Under typical pressures, it does not freeze at all, even at temperatures approaching absolute zero
The zero point energy is the minimum energy a particle or system always has, no matter what. Helium is the only substance that does not have a freezing point under ambient pressure, no matter the temperature.
These conditions have been created in a laboratory through evaporative cooling. The result is a colorless, highly compressible solid that is practically invisible
Which of the following will have the highest freezing point at one atmosphere?A: \\[0.1M\\] \\[NaCl\\] solutionB: \\[0.1M\\] sugar solutionC: \\[0.1M\\] \\[BaC{l [3]
Which of the following will have the highest freezing point at one atmosphere?. Hint: Freezing point refers to the temperature at which liquid and solid form of the same material/substance are said to be in equilibrium and possess the similar vapour pressure
The lowering of freezing point or freezing point depression is a colligative property which depends upon the number of the solute particles. As the number of particles increases, the freezing point decreases
Freezing point of the water keeps on lowering as more and more particles are appended till the point when salt stops getting dissolved. This is the reason that salt is employed for melting the ice and snow and also keeps them from re-freezing

Lowest freezing point room temperature liquid? [5]
What substance that is liquid at STP has the lowest freezing/melting point? I think it’s either 2-methylpentane or 3-methylpentane, but I get different numbers from different sources.. $\begingroup$ Comments are not for extended discussion; this conversation has been moved to chat
Sorting them by increasing melting point and checking the first few entries individually, it seems that N,N-diethylmethylamine holds the record, with a melting point of −196 °C (!) and a boiling point of 63 to 65 °C.. I also mentioned another possibility for very low melting liquid substances at room temperature, namely ionic liquids
Aldrich already offers multigram quantities of ionic liquids melting at −88 °C, and ongoing research offers even lower melting alternatives, such as the ones in Reiter et al. [1] which purportedly do not crystallize until −150 °C
Liquids – Freezing and Melting Points [6]
Common fluids and their freezing and melting points.. For pure compounds the following definitions can be given:
– Freezing point – the temperature at which a liquid turns into a solid. – The melting and freezing point changes with pressure, but normally they are given at 1 atm.
– For mixtures of compounds (as petroleum), there are ranges of melting and freezing points versus percent of the mixture melted or frozen.. – For a mixture, the initial melting point is close to the melting point of the lightest compound in the mixture, while the initial freezing point is close to the freezing point (or melting point) of the heaviest compound in the mixture.

Which aqueous solution has the lowest freezing point:. $0.5 \mathrm{m}$ glucose, $0.5 \mathrm{m} \mathrm{NaCl},$ or $0.5 \mathrm{m} \mathrm{CaCl}_{2} ?$
or $0.0150 \mathrm{m} \mathrm{Na}_{2} \mathrm{SO}_{4} ?$. Which aqueous solution would have the lowest freezing point?
Which of the following solution has the lowest freezing point and why? 0.1m glucose.01 m KCl, 0.1 m Na2SO4. from Chemistry Solutions Class 12 CBSE [8]
for any solution the partial vapour pressure of each volatile component in the solution is directly proportional to its mole fraction.. pA x xA where pA is vapour pressure of solvent having mole fraction xA.
the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution” and is expressed as:. Which of the following solution has the lowest freezing point and why? 0.1m glucose.01 m KCl, 0.1 m Na2SO4.
The solutions which obey Raoult’s law over the entire range of concentration are known as ideal solutions. The ideal solutions have two other important properties
Freezing-point depression [9]
Freezing-point depression is a drop in the maximum temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added. Examples include adding salt into water (used in ice cream makers and for de-icing roads), alcohol in water, ethylene or propylene glycol in water (used in antifreeze in cars), adding copper to molten silver (used to make solder that flows at a lower temperature than the silver pieces being joined), or the mixing of two solids such as impurities into a finely powdered drug.
The resulting liquid solution or solid-solid mixture has a lower freezing point than the pure solvent or solid because the chemical potential of the solvent in the mixture is lower than that of the pure solvent, the difference between the two being proportional to the natural logarithm of the mole fraction. In a similar manner, the chemical potential of the vapor above the solution is lower than that above a pure solvent, which results in boiling-point elevation
The freezing point is the temperature at which the liquid solvent and solid solvent are at equilibrium, so that their vapor pressures are equal. When a non-volatile solute is added to a volatile liquid solvent, the solution vapour pressure will be lower than that of the pure solvent
