# Ideal Gas in the Classroom: Quiet and Not Smelly?

In summary, An ideal gas is a theoretical gas composed of particles that have no volume and do not interact with each other. It is important to have a quiet and not smelly gas in the classroom for safety and comfort. An ideal gas differs from a real gas in that it does not exist in nature and only follows theoretical laws. Some examples of ideal gases include hydrogen, helium, and neon. The ideal gas law is used in the classroom to understand and predict the behavior of gases and can be used in experiments and demonstrations.
We were in our intro physics class and the prof was talking about ideal gas. He asked what are the qualities of ideal gas to which I replied "quiet and not smelly". Classroom exploded

Friend of mine once walked into class several minutes late, when asked by the teacher why he was late he very calmly announced "because I am not early."

## 1. What is an ideal gas?

An ideal gas is a theoretical gas composed of particles that have no volume and do not interact with each other. It follows the ideal gas law, which states that at a constant temperature and pressure, the volume of the gas is directly proportional to the number of particles present.

## 2. Why is it important to have a quiet and not smelly gas for classroom use?

Having a quiet and not smelly gas in the classroom is important for the safety and comfort of students and teachers. Loud or smelly gases can be distracting and potentially harmful to inhale in a confined space.

## 3. How is an ideal gas different from a real gas?

An ideal gas is different from a real gas in that it does not exist in nature and only follows theoretical laws. Real gases have volume and interact with each other, causing deviations from the ideal gas law at high pressures and low temperatures.

## 4. What are some examples of ideal gases?

Some examples of ideal gases include hydrogen, helium, and neon. These gases have low molecular weights and do not have strong intermolecular forces, making them good approximations of ideal gases.

## 5. How is the ideal gas law used in the classroom?

The ideal gas law is used in the classroom to understand and predict the behavior of gases in various situations. It can be used to calculate the volume, pressure, and temperature of a gas, as well as to compare the properties of different gases. It is also used in experiments and demonstrations to show the relationship between gas variables.
