“Do we have to convert the Celsius to Kelvin?” is the question that I probably heard the most common when solving practice problems on gas laws in class. And the short answer is yes, it is almost always necessary to … Read more
The ideal gas laws show the correlation of the temperature, pressure, volume, and the amount of a gas. It is derived from the individual gas laws such as the Boyle’s law, Charles’ law, etc. Remember, when discussing those, we used … Read more
The Avogadro’s Law studies the correlation between the amount of the gases (mole) and the volume of an ideal gas. To demonstrate it, we can use a pump equipped with a freely moving plunger that is filled with an ideal … Read more
The Gay-Lussac’s law demonstrates the relationship between the pressure and the temperature of an ideal gas. Let’s illustrate it by using a pump with a barrel that is held at a fixed position to prevent changing the volume. The pump … Read more
The Charle’s law shows the correlation between the temperature and the volume of an ideal gas. Let’s discuss it by using a pump with a freely moving plunger that is filled with some gas. In the experiment, we are going … Read more
In this post, we will discuss one of the gas laws using an illustration with a pump filled with some gas and a freely moving plunger and by changing the gas parameters determine their correlation. Boyle’s Law Boyle’s Law … Read more
In the previous post, we talked about the Graham’s law which shows that the rate of effusion of a gas is inversely proportional to the square root of its molar mass: \[{u_{{\rm{rms}}}}\;{\rm{ = }}\;\sqrt {\frac{{{\rm{3RT}}}}{{\rm{M}}}} \] One application … Read more
How do you know which ideal gas equation to use when solving a problem? Fortunately, there is a short answer to this, and it is the combined gas law equation: It allows you not to memorize all the … Read more
The following practice problems are to master to topics on the ideal gas laws: Boyle’s law, Charles’s law, and Avogadro’s Law, as well as the combined gas law equation. There are examples to work on the Dalton law of partial … Read more
Sometimes the amounts of gases need to be calculated based on chemical reactions. These calculations combine the ideal gas laws and the same principles we learn in stoichiometric calculations. The only difference for most problems is going to be that the … Read more
