Lesson: Pressure, Volume, and Temperature of an Ideal GasPhysics
In this lesson, we will learn how to calculate the pressure, temperature, and volume of an ideal gas using pV = NkT (the ideal gas law).

The number density of gas molecules is defined as the number of molecules present per unit volume. At a certain location in the space above Earth, the number density is m−3 and the atmospheric pressure at that location is N/m2. What is the temperature at this location?
Airtight bags containing food that are taken to high elevations become puffed up because the air inside the bags has expanded. A bag of pretzels was packed at a pressure of 1.00 atm and a temperature of . The bag is taken to a summer picnic in Santa Fe, New Mexico, where the air temperature is . The volume of the air in the bag is 1.24 times its volume when packed. What is the pressure of the air at the picnic?
A vacuum chamber does not produce a true vacuum but can produce a very low pressure of N/m2 at a temperature of . How many molecules per cubic centimeter remain in the vacuum chamber?
