Question

4.
Which one of the following gases
has the maximum value of root
mean square velocity
(A) CH4
(B) CO2
(C) H2
(D) CO2​

Answer 1

Answer:

(A) CH4

Explanation:

Methane (CH4) has the smallest molar mass (M), therefore it will have the largest room mean square speed (μrms).

Answer 2

(c).($H2$)  gases has the maximum value of root mean square velocity

Explanation:

$CH4$:

• Methane is a chemical molecule with the formula $CH4$ that is found in nature. It's a group hydride, the most basic alkane, and the primary component of natural gas.
• Atmospheric methane is formed when methane reaches the surface and enters the atmosphere.

$CO2$:

• Carbon dioxide is an acidic, colourless gas with a density that is roughly 53% that of dry air. A carbon atom is covalently doubly linked to two $CO2$oxygen atoms in a carbon dioxide molecule.
• It is found as a trace gas in the Earth's atmosphere.

$H2$:

• The chemical element hydrogen has the symbol $H$ and the atomic number.
• The lightest element is hydrogen. Hydrogen is a diatomic gas under normal conditions.
