Should remain the same, the volume will decrease.
Answer:
I believe it is hydrogen for the first and methane for the second.
Explanation:
Answer to 8: The most dangerous or harmful gas to humans in the atmosphere would be carbon dioxide. But reserchers have found that methane levels in ancient air samples and found that scientists have been vastly underestimating the amount of methane humans are emitting into the atmosphere via fossil fuels.
Answer to 7: The type of gases present are as critical to density as elevation and gravity, and all are interrelated. Certain atmospheric gases will create thick atmospheres. For example, atmospheres with abundant hydrogen tend to be thicker as gases will combine with hydrogen for greater mass.
Hope this helps!
Answer:

Answer : Carbon tetrachloride,
will show the greatest freezing point lowering.
Explanation :
For non-electrolyte solution, the formula used for lowering in freezing point is,
![\Delta T_f=k_f\times m](https://tex.z-dn.net/?f=%5CDelta%20T_f%3Dk_f%5Ctimes%20m)
where,
= lowering in freezing point
= molal depression constant
m = molality
As per question, the molality is same for all the non-electrolyte solution. So, the lowering in freezing point is depend on the
only.
That means the higher the value of
, the higher will be the freezing point lowering.
From the given non-electrolyte solutions, the value of
of carbon tetrachloride is higher than the other solutions.
Therefore, Carbon tetrachloride,
will show the greatest freezing point lowering.
