Question

State Gay-Lussac's law. How is it defined?

Answer 1

The pressure of a gas of fixed mass and fixed volume is directly proportional to the gas's absolute temperature. ... Some introductory physics textbooks still define the pressure-temperature relationship as Gay-Lussac's law.

Answer 2

When gases react they do so in volumes which bears a simple whole number ratio to one another and to the volumes of the products, if gaseous, provided the temperature and pressure of the reacting gases and their products remain constant.
