Question

use the following information to answer question 1.

a student uses a pump to fill their bike tire with air.

1. choose the row that identifies the type of pump the student used and the type of fluid that was pumped into the tire.

\

$$\begin{tabular}{|c|c|c|} \\hline row & type of pump & type of fluid \\\\ \\hline a. & hydraulic & liquid \\\\ \\hline b. & hydraulic & gas \\\\ \\hline c. & pneumatic & liquid \\\\ \\hline d. & pneumatic & gas \\\\ \\hline \\end{tabular}$$

<reasoning>

Identify the fluid used

The problem states that the student uses a pump to fill their bike tire with air. Air is a mixture of gases, so the type of fluid used is a gas.

Identify the type of pump

Pumps and systems that use compressed gas (like air) to transmit power or fill objects are called pneumatic systems. Systems that use liquids (like oil or water) are called hydraulic systems. Since this pump uses air, it is a pneumatic pump.

Match with the table rows

We look for the row in the table where the "Type of Pump" is "Pneumatic" and the "Type of Fluid" is "Gas". Row D matches both of these criteria.
