Certified Hyperbaric Technologist Practice Test

Question: 1 / 625

According to Boyle's Law, what happens to volume when pressure increases (assuming temperature remains constant)?

Increases proportionally

Decreases proportionally

Boyle's Law states that for a given mass of gas at constant temperature, the volume of the gas is inversely proportional to the pressure exerted on it. This means that as the pressure increases, the volume of the gas must decrease in order to keep the product of pressure and volume constant.

In practical terms, if you were to compress a gas within a closed container by applying more pressure, the gas molecules would be forced closer together, resulting in a reduction of volume. This relationship is crucial in many applications, including hyperbaric medicine, where understanding how gas behaves under pressure is essential for safe practices and treatments. Therefore, when pressure goes up, the volume goes down proportionally, confirming that the correct answer is that the volume decreases proportionally with an increase in pressure, while temperature is held constant.
