Introduction to Ideal Gasses Video Lessons

Concept

# Problem: Consider an ideal gas at 27.0°C and 1.00 atmosphere pressure. Imagine the molecules to be uniformly spaced, with each molecule at the center of a small cube. What is the length L of an edge of each small cube if adjacent cubes touch but don't overlap?

###### FREE Expert Solution

Ideal gas equation:

The ideal gas equation:

$\overline{){\mathbf{P}}{\mathbf{V}}{\mathbf{=}}{\mathbit{N}}{\mathbit{k}}{\mathbf{T}}}$, where N is the number of molecules, k = Boltzmann constant = 1.38066 × 10-23 J/K, and T is the temperature.

Rearranging, V = NkT/P
