Question

Imagine that you have two identical flasks, one containing 
chlorine gas and the other containing argon at the same 
temperature and pressure. How can you tell which is which 
without opening them?

Hello. Everyone in this video, we want to consider two identical clear flask, continuing different gasses at the same temperature, which is 70°C and same pressure. And this question was being asked. How can you differentiate burrowing gas from helium gas under these conditions. Again, these conditions is that we have the same temperature at 70°C and we have these same pressure. So since the container's temperature and pressure are identical for these two gasses, only the appearance at this point can be the point of comparison. So let's read option a option a reads burning gasses greenish while helium gas is colorless. So option is actually incorrect even though it does talk about the appearance. And that's wrong because burning gasses not greenish. The greenish yellow gasses, chlorine, helium gas is going to be colorless. And then for options be, this reads at the same temperature 70°C and pressure. Burning gas is indistinguishable from helium. And then option D here reads at 70 degrees Celsius. Burning gas appears very cloudy while helium gas is colorless. So of course B and D are incorrect because at the same temperature at 70 degrees Celsius and pressure burning gas can still be distinguished from helium as long as the floss is see through. As for brown and gas here running gas does not just look cloudy at 70 degrees Celsius browning is reddish brown. Gas while helium is colorless. So since very said that option A is incorrect as well as be and deem the only one left is option C. Let's see what option C says option. C reads at 70 degrees. Celsius Browning is reddish brown while helium is colorless, not exactly what we said. So our correct option is going to be answer choice C and that's going to be my final answer for this problem.
