# Gay lussac law mathematical relationship between mass

### Gay-Lussac's law - Wikipedia

Charles and Gay-Lussac's law relates the temperature and volume of an ideal gas. including the gas pressure, temperature (T), mass, and the volume (V) that The relationship between temperature and volume, at a constant number of. It states that, for a given mass and constant volume of an As a mathematical equation, Gay-Lussac's law is. Gay Lussac's law is the relationship between pressure and temperature of a gas. According to the Gay Lussac's Law, at constant volume, the pressure of a fixed mass of a gas is . For converting pressure in torr to atm, we use the relation.

Bread yeast have been selectively bred to eat sugar and burp carbon dioxide CO2.

When wheat flour and water are mixed together and kneaded, the protein molecules are mashed and stretched until they line up neatly to form a substance called gluten that, like chewing gum, is both elastic and plastic. Let this special matrix sit and the the CO2 vented from the yeast get trapped in thousands of tiny resilient, stretchy pockets. As this process continues these tiny pockets expand, which causes the volume of the dough to expand or rise in a process called proofing.

We now have a fluffy gummy blob ready for the oven. While there the dough expands again, but his time it's not due to the action of microorganisms they all die around the boiling point of water. This time it's the heat, or rather the temperature.

This domestic example illustrates quite nicely a fundamental property of gases. The volume of a gas is directly proportional to its temperature when pressure is constant. The experiment was repeated much later by Jacques Charles — in and much, much later by Joseph Gay-Lussac — in Charles did not publish his findings, but Gay-Lussac did. It is most frequently called Charles' law in the British sphere of influence and Gay-Lussac's law in the French, but never Amonton's law.

An isobaric process is one that takes place without any change in pressure. Let's recall what it means when two quantities are directly proportional like volume and temperature.

Heat up a gas and it's volume will expand.

Cool it down and it's volume will contract. The two quantities change in the same direction.

## Gay-Lussac's law

More specifically, an increase in one results in a proportional increase in the other and a decrease in one results in a proportional decrease in the other. For example… Doubling the absolute temperature of the air in an engine cylinder will double its volume.

Halving the absolute temperature of the air in a bag of potato chips will cause it to shrink to one half its original volume. The absolute temperature of a bread oven is one and a half times that of room temperature.

There's a symmetry at work here somewhere. A symmetry is a change in one quantity that leaves another, more fundamental quantity unchanged. This equation states that the product of the initial volume and pressure is equal to the product of the volume and pressure after a change in one of them under constant temperature.

For example, if the initial volume was mL at a pressure of torr, when the volume is compressed to mL, what is the pressure? Plug in the values: The Temperature-Volume Law This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. V Same as before, a constant can be put in: Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.

The Pressure Temperature Law This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. P Same as before, a constant can be put in: The Volume Amount Law Amedeo Avogadro Gives the relationship between volume and amount when pressure and temperature are held constant.

Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract.

If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases. V As before, a constant can be put in: The Combined Gas Law Now we can combine everything we have into one proportion: The volume of a given amount of gas is proportional to the ratio of its Kelvin temperature and its pressure.

Same as before, a constant can be put in: The Ideal Gas Law The previous laws all assume that the gas being measured is an ideal gas, a gas that obeys them all exactly.

But over a wide range of temperature, pressure, and volume, real gases deviate slightly from ideal. Since, according to Avogadro, the same volumes of gas contain the same number of moles, chemists could now determine the formulas of gaseous elements and their formula masses.
