# How do you determine which gas behaves most ideally?

## How do you determine which gas behaves most ideally?

Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles’ kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.

### Which gas would behave least ideally?

Sulfur dioxide should be the least volatile, have the greatest intermolecular interaction, and thus its behaviour is LEAST like the ideal.

#### At which pressure real gas will follow ideal behavior?

Only at relatively low pressures (less than 1 atm) do real gases approximate ideal gas behavior (Figure 10.9. 1b). Figure 10.9. 1: Real Gases Do Not Obey the Ideal Gas Law, Especially at High Pressures.

Why does high pressure deviate from ideal behavior?

The contribution of intermolecular forces creates deviations from ideal behavior at high pressures and low temperatures, and when the gas particles’ weight becomes significant.

Why does the ideal gas law break down at high pressure and low temperature?

The ideal gas law fails at low temperature and high-pressure because the volume occupied by the gas is quite small, so the inter-molecular distance between the molecules decreases. And hence, an attractive force can be observed between them.

## Why can you compress a real gas indefinitely?

The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles.

### Why you can compress gas easily but not liquid?

Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. Gas can be compressed much more easily than a liquid or solid.

#### What happens if you try to compress a solid?

In a solid, the atoms are very close together, and are in a fixed position. Applying pressure does not squeeze them into a smaller space. If you apply enough pressure, you may cause the solid to break, or you may bend it into a different shape, but it will not get any smaller.

Can a gas change shape?

A gas and a liquid will change shape to fit the shape of their container. A gas will change volume to fit the volume of the container. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them.

What is the 3 state of matter?

There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.

## Why the force of attraction between solid particles is stronger?

Answer: Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other.

### Which state of matter has the least number of intermolecular forces?

gaseous state

#### Which bond is available in the three state of matter?

The three states of matter are: Solids: The strong bonds between molecules make solids rigid and very difficult to deform. Liquids: The relatively weak bonds between molecules allow liquids to be deformed without effort.

Which state of matter has the most energy?

gas

What is the highest potential energy?

gravitational potential energy

## Which state of matter moves the fastest?

Phases of matter

A B
molecules move fastest in this phase plasma
molecules move faster than liquids in this state gas
molecules move the slowest in this state solid
molecules move around each other in this state liquid

### Which state has minimum amount of energy?

Matter in its solid state has the lowest amount of thermal energy (for that type of matter). Because solids have less thermal energy than liquids or gasses, the atoms in their solid state move very little.

#### What is the minimum energy?

The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium. An isolated system has a fixed total energy and mass.

Which state of matter has the most energy explain with diagram?

The gas state of matter has the most energy because of how freely the molecules move. Matter is a physical substance of which there are three, and they are solid, liquid, and gas. Solid matter is very compact with the particles very close together and not much movement; therefore, no action, no energy.

What is the minimum energy required to break the egg?

approximately 0.25 J

## How many pounds does it take to crush an egg?

5 ½ pounds

### Why does an egg not break when you squeeze it?

The egg’s unique shape gives it tremendous strength, despite its fragility. That’s why the egg doesn’t break when you add pressure to both ends. The curved form of the shell also distributes pressure evenly all over the shell rather than concentrating it at any one point.

#### Does the final speed depend on the steepness of the hill?

Challenge: With no friction, you can use the relationship between potential and kinetic energy to predict the velocity of the car at the bottom of this hill from its starting height. With no friction, does the final velocity depend on the steepness of the hill? No D.
