Question

A scientist is measuring the pressure that is exerted by each of the following gases in the atmosphere: carbon dioxide, oxygen, and nitrogen. Which term most likely describes what she is measuring? final pressure atmospheric pressure combined pressure partial pressure

Answer 1

Hello!

The term that most likely describe what the scientist is measuring is partial pressure

Why?

Final Pressure: Represents the pressure of a gas after it undergoes a change in temperature or volume.

Atmospheric Pressure: Represents the pressure of all the gases in the atmosphere over the Earth's surface.

Combined Pressure: Represents the sum of the pressure of all the gases in a system.

Partial Pressure: Represents the individual contribution to the overall pressure of a gas in a mixture of gases.

The Earth's atmosphere is composed of a mixture of gases, namely Carbon Dioxide (CO₂), Oxygen (O₂), Nitrogen (N), and other trace gases. If the scientist want to know the individual pressure exerted by each of these gases, she'll need to measure the partial pressure of each gas.

Have a nice day!

Answer 2

Because the pressure of each gas was measured, that means that partial pressure was measured. ( pressure of part)
We have parts as carbon dioxide, oxygen and nitrogen, and pressure was measured separately for each part.
