Two gases CH4 and SO2 effuse through a tiny opening. Which will move faster?

The rate of effusion is inversely proportional to the square root of the molar mass (Graham's Law).
Put another way, the small, lighter weight gas will move faster than the heavier gas.
Molar mass CH4 = 16 g/mol.
Molar mass SO2 = 48 g/mol
Thus, CH4 will move faster.

Does a lighter gas effuse slower than heavier gases?
yup
Why gases have higher chance of leaking through holes?
Gas leaking through a small hole in its container is called effusion. The rate of effusion depends upon molar mass. The smaller the molar mass, the more quickly a gas will effuse out. Given these gases: He, Ar, CO2, helium will effuse out the fastest because its molar mass is only 4 (compared to 40 for argon and 44 for carbon dioxide.)
Waves are known to travel faster through solids than they do through gases?

Why do some gases travel faster than others?
some gases travel faster than other gases due to the gases density and the energy of the medium that the gase is traveling through.
A volcanic vent or opening through which gases and smoke come out of is called a?
fumarole
What is a sentence for the word stomata?
A stomata is an opening allows gases to come through.
What is an opening in earths crust through which gases and melted rock pass?
volcano
What is a fumerole?
An opening in or near a volcano, through which hot sulfurous gases emerge.
What type of gas molecules diffuse and effuse faster?
As stated by Graham's law this depends on the mass of the gas molecule, there is an inverse relationship the bigger the mass the slower the effusion rate so molecules with a lower molar mass effuse faster.
What is the opening called in the earths crust called through which lava gases and other pieces of rock erupt?
A volcano is the opening called in the earths crust called through which lava gases and other pieces of rock erupt.
