Question

What does the graph say about the relationship between pressure and volume in a gas?

Select the correct answer from each drop-down menu.
As the gas volume increases, the pressure
proportional to the volume.
The pressure in a gas is

Answer 1

Answer: The pressure of gas is inversely proportional to volume of the gas.

Explanation: A pressure-volume graph for gases demonstrates the relationship between pressure and volume. When the volume decreases, the pressure increases (inverse relationship) and vice versa. The graph visually represents the behavior of gases during compression or expansion processes. The slope of the line on the graph indicates the gas's compressibility. Analyzing the graph provides insights into gas properties and processes, such as Boyle's Law or the ideal gas law, in a concise and graphical manner.

Therefore the answer is pressure decrease as volume increase.
