What will happen to the volume if the number of moles of a gas is decreased at constant temperature and pressure? The volume will increase. The volume will decrease. The volume will remain the same. The volume will be negative.

The ideal gas law states that PV = nRT. Therefore, if pressure P and temperature T are held constant, and the number of moles n is decreased, the right-side value of the equation decreases. To compensate, volume V must decrease as well. This is the second choice.

Answer:

The volume will decrease.

Explanation:

The number of moles of a gas is directly proportional to its volume according to Avogadro's law. Hence volume increases as number of moles increases. Volume also decreases as number of moles decreases.

Hence according to the question, when the number of moles of a gas decreases, the volume of the gas also decreases along side in obedience to the Avogadro's law.
