## What are the assumptions for an ideal gas?

For a gas to be considered “ideal”, there are four assumptions. Gas particles have equal sizes and are not subject to intermolecular forces (attraction/repulsion) with other gases particles. The motion of the gas particles is in accordance with Newton’s Laws of Motion.

**Which of the following is not an essential assumption for an ideal gas? **

Which of the following assumptions is not made in the kinetic theory for gases? The volume of the gas molecules is negligible. The attraction force between molecules is negligible.

### Which of the following is not true about ideal gas molecules?

There is no interaction between molecules. It can’t be made into liquid. All molecules of the gas move at the same speed. PV is proportional the gas’s volume at a given temperature.

**What is an ideal gas 1 point? **

An ideal gas is a hypothetical gas that contains many random moving point particles and is not subject to interparticle interaction. If the interaction is completely elastic or considered point-like collisions, then it is possible to relax the requirement for zero interaction.

## What is CP and CV in thermodynamics?

In thermodynamics, heat capacity ratio (or ratio of specific heat capabilities) is also called the adiabatic indicator. It is the sum of two specific heat capacities Cp and Cv. These are: Heat Capacity At Constant Pressure (Cp), Heat capacity at Constant Voltage (Cv )

).

**What do you mean by compressibility factor? **

It measures how far the thermodynamic properties a real gas differ from those of an ideal gas. It can be described as the ratio between the actual volume and the volume predicted for an ideal gas at the same temperature, pressure, and volume.

### Is an ideal gas compressible?

All gases, even ideal gases, can be compressed. Because the molecules of gases are so far apart, they can easily be combined by pressure.

**How do you find the compressibility factor for a gas mixture? **

The Z-factor for any hydrocarbon gas (dry or rich) can be calculated in just two steps. The Z-factor for pure methane must first be calculated. Next, the Z factor of richer gases can be calculated. You can calculate the compressibility factor for pure methane by using the correlation in Eq. 14 as following.
