Question

Is Avogadro's Law direct or inverse.

Answer 1

Early scientists investigated the relationships between a gas's pressure (P) and its temperature (T), volume (V), and amount (n) by keeping two of the four variables constant (for example, amount and temperature), varying a third (for example, pressure), and measuring the effect of the change on the fourth (in this case, volume). Several good instances of the scientific process may be found in the history of their discoveries.

Complete answer:
Avogadro's law is an experimental gas law that describes the relationship between the volume of a gas and the amount of gas component present. The legislation is an example of the ideal gas law in action. "Equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules," according to Avogadro's law. If the temperature and pressure remain constant, the volume and quantity (moles) of an ideal gas are precisely proportional to its mass. The rule is named after Amedeo Avogadro, who proposed in 1812 that two identical samples of an ideal gas with the same volume, temperature, and pressure have the same number of molecules.
When equal quantities of gaseous hydrogen and nitrogen are at the same temperature and pressure, they contain the same number of atoms and exhibit perfect gas behaviour. In fact, real gases deviate somewhat from the ideal behaviour, thus the rule only holds roughly, but it is still a helpful approximation for scientists. Where V is the volume of the gas; n is the amount of material in the gas (measured in moles); and k is a constant for a particular temperature and pressure, the law may be stated as follows: $\dfrac{V}{n}=k$
Under the same temperature and pressure, equal quantities of all gases contain the same number of molecules, according to this rule.
The law can be effectively stated as follows when comparing the same material under two distinct sets of conditions: $\dfrac{{{V}_{1}}}{{{n}_{1}}}=\dfrac{{{V}_{2}}}{{{n}_{2}}}$

Note:
The equation demonstrates that as the number of moles of gas grows, so does the volume of the gas. Similarly, when the number of moles of gas is reduced, the volume is reduced as well. As a result, the number of molecules or atoms in a given volume of ideal gas is unaffected by their size or the gas's molar mass. According to Avogadro's Law, the volume of a confined gas is exactly proportional to the number of moles under constant temperature and pressure.
