Question

question 4 of 30
the graph below shows how the pressure and volume of a gas vary when the number of moles and the temperature of the gas are held constant. what happens to the pressure inside a sealed syringe of gas as the volume of the syringe increases?
graph
a. the pressure increases and then decreases.
b. the pressure remains the same.
c. the pressure increases.
d. the pressure decreases.

Explanation:

The graph shows the relationship between pressure (P) and volume (V) of a gas at constant temperature and moles (Boyle's Law context). The curve is a hyperbola, indicating an inverse relationship: as volume (V) increases, pressure (P) decreases. So when the syringe's volume (gas volume) increases, pressure inside decreases.

Answer:

D. The pressure decreases.
