Question

The atmosphere of Venus is mostly carbon dioxide, and the atmosphere of the Earth has water vapor. Why are these two gases absent in the atmosphere of the satellite around Saturn called Titan

Answer 1

Titan's atmosphere lacks carbon dioxide and water vapor because its extremely low temperatures cause these substances to freeze solid, leaving an atmosphere primarily composed of nitrogen.

Step-by-step explanation:

The primary reason that carbon dioxide and water vapor are absent in the atmosphere of Saturn's moon Titan is due to the extremely low temperatures present on this celestial body. On Titan, temperatures are so cold that both CO₂ and water are frozen solid, thereby precluding their existence as gases in the moon's atmosphere. Instead, Titan's atmosphere consists mostly of nitrogen, as it was able to retain volatile compounds like ammonia, methane, and nitrogen which can remain gaseous at much lower temperatures.

Answer 2

if these gases existed in Titan, this n in solid form, by which its absence in the atmosphere is understood.

Step-by-step explanation:

Each gas and chemical compound has a defined temperature for changes of state, specifically for the change from gaseous to liquid and from liquid to solid state we have

gas gas → liquid liquid → solid

(ºC) (ºC)

H₂0 (Water) 100 0

CO₂ -56.6 (P> = 5.2 bar) <-56.6

The temperature of the Titan satellite is - 180ºC

From the above, if these gases existed in Titan, this n in solid form, by which its absence in the atmosphere is understood.
