Question
Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules- this statement was given by which law?
- Avogadro's law
- Gay-Lussac's law
- Boyles law
- Charles law
Hint:
Same number of molecules is related to Avogadro's law.
The correct answer is: Avogadro's law
- Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it.
- Charles's Law is an ideal gas law where at constant pressure, the volume of an ideal gas is directly proportional to its absolute temperature.
- Gay-Lussac's law is an ideal gas law which states that at constant volume, the pressure of an ideal gas is directly proportional to its absolute temperature (in Kelvin).
- Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules- this statement was given by Avogadro's law.
