Questions and Answers

What is the definition of Gay Lussac's Law?

The spontaneous spreading out of a substance due to the natural movement of its particles.

What is the relationship between the volume of a gas and its pressure at constant temperature according to Boyle's Law?

The volume of a gas is inversely proportional to the pressure of the gas.

What is Avogadro's Law, and what does it state about equal volumes of gases?

Avogadro's Law states that equal volumes of gases, under the same conditions of temperature and pressure, contain equal numbers of molecules.

What is the relationship between the volume of a gas and its temperature at constant pressure according to Charles' Law?
