Question

A gas or vapor can be treated as an ideal gas, if:

1) Its molecules occupy negligible volume compared to the total volume of the gas
2) Its molecules do not exert any forces on each other
3) Its molecules have elastic collisions with each other and the walls of the container
4) All of the above

Answer 1

A gas is treated as an ideal gas if its molecules occupy negligible volume, exert no forces on each other, and have elastic collisions, all of which are satisfied under conditions of low pressure and high temperature.

Step-by-step explanation:

A gas or vapor can be treated as an ideal gas if all of the following conditions apply:

• Its molecules occupy negligible volume compared to the total volume of the gas.
• Its molecules do not exert any forces on each other.
• Its molecules have elastic collisions with each other and the walls of the container.

Ideal gas behavior is a hypothetical assumption useful for explaining and predicting the properties of gases under certain conditions, primarily at low pressure and high temperature. Kinetic molecular theory helps define the traits of an ideal gas, which assumes no volume and no intermolecular attractions between particles, something closer to a reality for real gases at typical laboratory conditions of temperature and pressure.
