Avogadro's hypothesis
Avogadro's Hypothesis states that equal volumes of gases, at the same temperature and pressure, contain the same number of molecules, regardless of their chemical identity. For example, if you have a balloon filled with hydrogen gas and another balloon of the same size filled with oxygen gas, and both are at the same temperature and pressure, they will have the same number of molecules inside, even though they are different gases. This principle helps us understand the behavior of gases and is fundamental in chemistry, especially when dealing with reactions involving gases.

Avogadro's hypothesis states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules. This means that if you have two balloons of gas that are the same size and temperature, they have the same number of particles, regardless of what type of gas they are. This principle helps us understand the relationship between gas volume and the amount of substance, forming the foundation for the concept of the mole in chemistry, which is crucial for quantifying chemical reactions and gas behavior.
