Question & Answer
Choose the Best Answer
The pressure decreases.
The pressure increases.
The pressure remains the same.
The pressure fluctuates randomly.
Understanding the Answer
Let's break down why this is correct
Pressure falls when volume goes up because the gas molecules are spread over a larger space. Other options are incorrect because Some people think that more space means more frequent hits, but the opposite occurs; The belief that pressure stays the same because temperature is unchanged ignores Boyle's Law.

Definition
The Ideal Gas Law states that for one mole of gas at room temperature and one atmosphere pressure, the volume is approximately 24 liters, regardless of the gas type. This law defines the relationship between pressure, volume, temperature, and the number of gas molecules, providing a basis for understanding gas behavior in various conditions.
