Question

The diagram shows a pump connected to a glass jar. The volume of the glass jar is $400$ $c{m}^3$ and it is filled with air. When the piston is pushed in completely, $50$ $c{m}^3$ of air is forced into the jar.
What is the final volume of air in the jar?

• A. $50$ $c{m}^3$
• B. $100$ $c{m}^3$
• C. $400$ $c{m}^3$
• D. $450$ $c{m}^3$

Answer 1

The correct option is C $400$ $c{m}^3$

As air can be compressed and takes up the volume of container, its final volume in the jar will be $400$ $c{m}^3$.
