Multiple Choice

Which of the following statements is true about the composition of the atmosphere according to the Ideal Gas Law?

The Ideal Gas Law assumes that gases in the atmosphere behave ideally under all conditions.

The Ideal Gas Law relates pressure, volume, temperature, and moles of gas, but does not specify the composition of the atmosphere.

The Ideal Gas Law accounts for the interactions between different gases in the atmosphere.

The Ideal Gas Law can be used to determine the exact composition of the atmosphere.

Verified step by step guidance

Begin by understanding the Ideal Gas Law, which is expressed as \( PV = nRT \). This equation relates the pressure \( P \), volume \( V \), temperature \( T \), and moles of gas \( n \), with \( R \) being the ideal gas constant.

Recognize that the Ideal Gas Law assumes gases behave ideally, meaning they have no intermolecular forces and occupy no volume themselves. This is an approximation that works well under certain conditions, such as low pressure and high temperature.

Consider the statement that the Ideal Gas Law does not specify the composition of the atmosphere. This is true because the law provides a relationship between the physical properties of gases but does not account for the specific types or proportions of gases present.

Evaluate the statement that the Ideal Gas Law accounts for interactions between different gases. This is incorrect because the law assumes no interactions between gas molecules, which is a characteristic of ideal gases.

Understand that while the Ideal Gas Law can be used to calculate properties like pressure or volume for a given amount of gas, it cannot determine the exact composition of the atmosphere, as it does not differentiate between different types of gases.
