Chapter 1.2, Problem 1.28E

To determine

To describe if filling car tires with nitrogen of compressed air increase gas mileage.

Explanation of Solution

Most of the cars are using compressed air instead of nitrogen. Therefore, it is better to make one of the experiments to answer this question. Select some cars of different brand. Divide it in two groups. Half of the cars in one group and half cars in group 2. Suppose in Group 1, we filled a nitrogen and in group 2 we used compressed air. For both groups need to compare the mileage and then decide the which has higher mileage.
