Ideal gas Assumptions

Postby 205538966 » Sun Feb 18, 2024 9:19 pm

What do we have to assume when we are told that a compound acts as an ideal gas?

Ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume)

When we say that a gas is ideal, we assume that there are no intermolecular attractions or repulsions between the gas particles, that they are all equally sized and of negligible mass, and that their collisions are elastic. Also, the gas will expand to fill its entire container and the average kinetic energy of the particles is proportional to temperature.

basically what you'd want a gas to be when doing calculations: "ideal." So there aren't extraneous variables that you have to take into account, such size, mass, interactions with each other, etc., as our peers stated

Hi, when a compound is assumed to function as an ideal gas, we assume a small volume of gas particles, no intermolecular interactions, random motion, elastic collisions, and high temperature and low pressure.Hope this helps!!
