Question

What conditions of a gas sample ought to remain constant for Avogadro's law to be used?

1) volume
2) amount
3) temperature
4) pressure

Answer 1

Avogadro's Law states that at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas in the sample.

Step-by-step explanation:

Avogadro's Law states that at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas in the sample.

In other words, if the temperature and pressure of a gas remain constant, increasing the number of gas molecules (moles) will also increase the volume of the gas sample. Therefore, to use Avogadro's Law, the conditions of the gas sample that should remain constant are volume, temperature, and pressure.
