Yes, argon (Ar) has a boiling point of -186°C, while helium (He) has a boiling point of -268.9°C, meaning helium boils at a lower temperature than argon.
NaCl solution freezes at lower temp. than water but boils at higher temp.than water
At STP, Helium (He) will diffuse more readily than the other gases listed (Ne, Ar, Kr, Xe) due to its smaller atomic size and lower molecular weight, resulting in higher average velocity of gas molecules and thus faster diffusion rates.
Chlorine.
There are more than two isotopes....
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.

Yes, if you replace the upper receiver.
i guess because human population is higher than ever so people want their children and grandchildren to have a good future.
The AR 15 is a rifle, not a caliber. the .223 is a caliber. Usually the AR-15 is made in caliber .223.
If VE+AR+MK+MC is better than 235, or AR+MK+EI+GS is better than 235, then you must take the NAPT (Navy Advanced Programs Test) to achieve: VE+AR+MK+MC+NAPT = 290 (with minimum 50 NAPT score) or AR+MK+EI+GS+NAPT=290 (with minimum 50 NAPT score). If VE+AR+MK+MC is better than 252, or AR+MK+EI+GS is better than 252, no NAPT is required.
Hydrogen peroxide AR (Analytical Reagent) grade is of higher purity compared to LR (Laboratory Reagent) grade. AR grade typically has a purity of 95-97%, while LR grade has a purity of around 70%, making AR grade more suitable for analytical and research applications where higher purity is required.
At STP, Helium (He) will diffuse more readily than the other gases listed (Ne, Ar, Kr, Xe) due to its smaller atomic size and lower molecular weight, resulting in higher average velocity of gas molecules and thus faster diffusion rates.
Depends entirely upon pressure. At one atmosphere, Ar liquifies at -186C
