Question

An expandable container is filled with hydrogen gas and oxygen gas. Hydrogen gas has a partial pressure of 0.75 atm and oxygen gas has a partial pressure of 1.45 atm. Which of the diagrams (A–C) represents the change in volume of the container when the Kelvin temperature is decreased by half and the number of gas molecules is doubled at constant pressure?

Diagram A: An oval container with gas particles, representing volume change.

Accepted Answer

Diagram D: A narrow oval container with gas particles, illustrating a distinct volume change.

Answer

Diagram B: A circular container with gas particles, showing a different volume change.

Answer

Diagram C: An elongated oval container with gas particles, indicating another volume change.
