Question

How is the gay lussac's law applied in the candle experiment?

Answer 1

Explanation:

Gay's law (more correctly referred to as Amontons's law) states that the pressure of a given mass of gas varies directly with the absolute temperature of the gas, when the volume is kept constant.[1]

Mathematically, it can be written as: {\displaystyle {\frac {P}{T}}=k}{\displaystyle {\frac {P}{T}}=k}. It is a special case of the ideal gas law.

Gay-Lussac is incorrectly recognized for the Pressure Law which established that the pressure of an enclosed gas is directly proportional to its temperature and which he was the first to formulate (c. 1809).[2] He is also sometimes credited[3][4][5] with being the first to publish convincing evidence that shows the relationship between the pressure and temperature of a fixed mass of gas kept at a constant volume.[4]

These laws are also known variously as the Pressure Law or Amontons's law and Dalton's law respectively.

Answer 2

Gay-Lussac's Law is a gas law that states that the pressure of a fixed amount of gas at a constant volume is directly proportional to its absolute temperature. This law is commonly applied in various experiments involving gases, including the candle experiment.

• In the candle experiment, Gay-Lussac's Law is used to explain the relationship between the temperature of the gas and the pressure inside the container. When a candle is lit inside a container, it heats the air inside, causing the gas molecules to move faster and collide more frequently with the walls of the container. This increase in molecular collisions results in an increase in the pressure of the gas inside the container.

• Gay-Lussac's Law explains that this increase in pressure is directly proportional to the increase in temperature of the gas. Therefore, as the temperature of the gas inside the container increases due to the burning candle, the pressure also increases. This can be observed by using a pressure gauge or by measuring the height of a column of water inside a manometer.

In summary, Gay-Lussac's Law is used in the candle experiment to explain the relationship between the temperature of the gas and the pressure inside the container.
