• 9 What relationship does Avogadro law describe apex? What relationship does Avogadro law describe apex? Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules,

• This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.
• What relationship does Boyle’s law describe? Boyle’s law is a connection between pressure and volume,
• It asserts that under constant temperature, the pressure of a specific quantity of gas is inversely proportional to its volume.

What is the relationship for the two variables in Charles Law? In Charles’ law, the relationship between Temperature (T) and Volume (V) is analyzed. The form of Charles’ law is: V = k*T, where k is a constant and the pressure is constant. In this equation the mass is constant and the air is confined to a compressible and expandable volume.
Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules, This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas,

1. The law is approximately valid for real gases at sufficiently low pressures and high temperatures.
2. The specific number of molecules in one gram- mole of a substance, defined as the molecular weight in grams, is 6.02214076 × 10 23, a quantity called Avogadro’s number, or the Avogadro constant,
3. For example, the molecular weight of oxygen is 32.00, so that one gram-mole of oxygen has a mass of 32.00 grams and contains 6.02214076 × 10 23 molecules.

The volume occupied by one gram-mole of gas is about 22.4 litres (0.791 cubic foot) at standard temperature and pressure (0 °C, 1 atmosphere) and is the same for all gases, according to Avogadro’s law. The law was first proposed in 1811 by Amedeo Avogadro, a professor of higher physics at the University of Turin for many years, but it was not generally accepted until after 1858, when an Italian chemist, Stanislao Cannizzaro, constructed a logical system of chemistry based on it.

#### What relationship does Avogadro and law describe?

What relationship does Avogadro’s law describe? – A modern statement is: Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
