4. A gas exerts a pressure of 7 kPa on the wall of the container. When the container is emptied into a 15 L container, the pressure exerted by
the gas increases to 17 kPa. Find the volume of the first container.
Assume temperature stays constant.

36 L

Explanation:

Step 1: Given data

Step 2: Calculate the volume of the first container

If we assume ideal behavior and constant temperature, we can calculate the volume of the first container using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₁ = P₂ × V₂ / P₁

V₁ = 17 kPa × 15 L / 7 kPa = 36 L

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
