A Hypothetical Situation Involving Gases

In summary, the question asks what would happen if the empty space in the universe was filled with gases found in Earth's atmosphere, without taking into account gravity from massive objects. The answer is speculative, as interstellar space already contains some gas and material, but if it were denser, more stars and systems may form. However, this would also likely result in a collapse of the universe due to the increased gravity.

What would happen if all of the empty space of the universe from the small to the vast, were replaced with the gases that make the Earth's atmosphere while neglecting gravity from any massive object?

Welcome to PF!

This question is so anti-reality speculative that I don't know that any possible answer exists...or, rather, since you're making it up, you may as well just make-up the answer yourself as well. Sorry. Would you like to try to make the question more realistic?

Interstellar space already does contain a lot of gas (and dusty bits of other material), though nothing like as dense as the Earth's atmosphere.
The denser regions are the places where new stars and planets form.
If interstellar space contained a much greater density of stuff, I would expect that many more stars and systems would form then we see.
But then all that additional mass would probably result in a universe which collapses pretty quickly due to the hugely much greater gravity ( as a whole) in it.

Related to A Hypothetical Situation Involving Gases

1. What is a hypothetical situation involving gases?

A hypothetical situation involving gases is a theoretical scenario that involves the behavior and properties of gases in different conditions. It allows scientists to make predictions and study the effects of changing variables on the behavior of gases.

2. How are gases affected by changes in temperature and pressure?

Gases are highly affected by changes in temperature and pressure. As temperature increases, the molecules of gas move faster and collide more frequently, resulting in an increase in pressure. On the other hand, as pressure increases, the volume of gas decreases, and the temperature also increases due to the increase in molecular collisions.

3. What is the ideal gas law and how is it used in a hypothetical situation?

The ideal gas law is a mathematical equation that describes the relationship between pressure, volume, temperature, and the number of moles of a gas. It is used in a hypothetical situation involving gases to predict the behavior of gases under different conditions and to compare it with real-world observations.

4. How does the behavior of gases change at different altitudes?

The behavior of gases changes at different altitudes due to changes in temperature and pressure. As altitude increases, the air becomes less dense, which leads to a decrease in pressure. This decrease in pressure causes the temperature to decrease as well, resulting in a decrease in the number of molecular collisions.

5. What are some real-world applications of studying gases in a hypothetical situation?

Studying gases in a hypothetical situation has many real-world applications. It helps in predicting and understanding the behavior of gases in industrial processes, such as in chemical reactions and gas storage. It also aids in predicting the effects of air pollution and climate change, as well as in the development of new technologies, such as fuel cells and gas-powered vehicles.
