Question:
Which one of the following gases is the major contributor to global warming?
Which one of the following gases is the major contributor to global warming?
Show Hint
CO2 is the main driver of global warming due to human activities like fossil fuel burning and deforestation.
Updated On: Mar 18, 2026
- CO
- CO2
- CH4
- N2O
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
CO2 is the most significant greenhouse gas due to its high concentration and persistence in the atmosphere. It absorbs infrared radiation and traps heat. While CH4 and N2O are stronger per molecule, their overall concentration is far less than that of CO2.

Two statements are given below: Statement-I: The ratio of the molar volume of a gas to that of an ideal gas at constant temperature and pressure is called the compressibility factor.
Statement-II: The RMS velocity of a gas is directly proportional to the square root of \( T(K) \).- Identify the correct statements from the following:
(I) According to Charles' law, at constant pressure, the volume of a gas is directly proportional to its temperature.
(II) The rate of diffusion of a certain mass of a gas is inversely proportional to its density, at constant pressure and temperature.
(III) The kinetic energy of a gas is directly proportional to T (K). - At 300 K, 1 g of an ideal gas (A) exerted a pressure of 2 atm in a closed container. When 2 g of another ideal gas (B) was introduced into this container at the same temperature, the pressure changed to 3 atm. The correct relationship between the molar mass of A (\(M_A\)) and B (\(M_B\)) is:
- The vapors of 1 g of an element occupy 2.5625 L exerting a pressure of 0.5 atm at 1000 K. What is the molar mass (in $\text{g mol}^{-1}$) of the element? (Assume vapors follow ideal gas equation. Given $R = 0.082 \text{ L atm mol}^{-1} \text{K}^{-1}$)
