Is the air in a room an ideal gas? How do you know this?
How does this compare to the density of air at room temperature?
thanks

An ideal gas is a theoretical concept used in physics and chemistry to describe the behavior of gases. It is a hypothetical gas that follows the ideal gas law, which states that the pressure, volume, and temperature of a gas are all directly proportional to each other.
In most cases, the air in a room can be approximated as an ideal gas. This is because air is made up of small particles (molecules) that are widely spaced apart, and their interactions with each other are minimal. However, at very high pressures or low temperatures, the behavior of air may deviate from that of an ideal gas.
The ideal gas law assumes that the gas particles have no volume and do not interact with each other. It also assumes that the gas particles are in constant, random motion and that their collisions with each other and with the walls of the container are perfectly elastic. Additionally, it assumes that the gas particles have negligible forces of attraction between them.
The ideal gas law, PV = nRT, can be used to describe the behavior of the air in a room by measuring the pressure (P), volume (V), temperature (T), and number of moles (n) of gas present. This allows us to calculate any one of these variables if we know the values of the other three.
Some common examples of ideal gases include air, helium, neon, and hydrogen. These gases behave very closely to the ideal gas law under normal conditions, making them useful for practical applications such as in refrigerators and air conditioners.
