A region of the earth’s atmosphere contains n molecules (treated as ideal gas molecules) per unit volume. The temperature of air in the region is T. If k represents Boltzmann’s constant and R represents universal gas constant, the pressure of air in the region is
  • a)
    RT/n
  • b)
    nRkT
  • c)
    nkT
  • d)
    nT/k
Correct answer is option 'C'. Can you explain this answer?

PV = nRT
Where n = number of moles = m/NA
So, P = (m/V)(R/NA)T
Also, we know that R/NA = k
So, P = nkT

A region of the earth refers to a specific area or part of the planet. It can be defined based on geographical, cultural, political, or ecological characteristics. Regions can be as large as continents or as small as local neighborhoods. They can also be defined based on specific criteria such as climate, language, religion, or economic activities. Examples of regions include the Amazon Rainforest, the Sahara Desert, the European Union, or the Pacific Northwest in the United States.
