Question

which law states that the volume of a given amount of gas is proportional to temperature when pressure and number of moles remain constant

Answer 1

Charle's Law. Volume is directly proportional to the absolute temperature when pressure is constant.

Answer 2

Answer: The correct answer is Charles' law.

Explanation:

There are 4 laws of gases:

• Boyle's Law: This law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto \frac{1}{V}$     (At constant temperature and number of moles)

• Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$     (At constant pressure and number of moles)

• Gay-Lussac's Law: This law states that pressure is directly proportional to the temperature of the gas at constant volume and number of moles.

$P\propto T$     (At constant volume and number of moles)

• Avogadro's Law: This law states that volume is directly proportional to the number of moles of the gas at constant pressure and temperature.

$V\propto n$   (At constant temperature and pressure)

Hence, the correct answer is Charles' law.
