Avogadro's law is an experimental gas law relating the volume of a gas to the amount of substance of gas present. The law is a specific case of the ideal gas law. A modern statement is: Avogadro's law states that, "equal volumes of all gases, at the same temperature and p
Answer:◇ Avogadro's law is the relation which states that at the same temperature and pressure, equal volumes of all gases contain the same number of molecules. The law was described by Italian chemist and physicist Amedeo Avogadro in 1811.
Avogadro's Law Equation
There are a few ways to write this gas law, which is a mathematical relation. It may be stated:
k = V/n
where k is a proportionality constant V is the volume of a gas, and n is the number of moles of a gas
Avogadro's law also means the ideal gas constant is the same value for all gases, so:
constant = p1V1/T1n1 = P2V2/T2n2
V1/n1 = V2/n2
V1/n2 = V2/n1
where p is pressure of a gas, V is volume, T is temperature, and n is number of moles
Implications of Avogadro's Law
There are a few important consequences of the law being true.
◇ The molar volume of all ideal gases at 0°C and 1 atm pressure is 22.4 liters.
◇ If pressure and temperature of a gas are constant, when the amount of gas increases, the volume increases.
◇ If pressure and temperature of a gas are constant, when the amount of gas decreases, the volume decreases.
◇ You prove Avogadro's Law every time you blow up a balloon.
