In physics, the distance of a moving object can be found using the following kinematic equation: =+2∗ where d is distance, vi is the initial velocity, vf is the final velocity, and t is the time spent moving. Rearrange this equation to find another equation that solves for the initial velocity vi.

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
