Gases

gases are compressible, gases epand as the temperature increases, gases have very little viscosity, gases mix evenly and gases have low density.

• ideal gas is a fake gas that obeys all gas laws under any conditions.
• a real gas deviates from an ideal gas under certain conditions.
• (real gases act just like ideal gases at stp and satp conditions)

• 1. infinently compressible.
• 2. gas molecules are constantly in random motion because no force exists in between them.
• 3. when gas molecules collide no energy is lost.

• 1. at high temps, molecules are forced closer together and their size becomes significant.
• 2. as temp decreases molecules slow down, stick together and cause the gas to become a liquid because of intermolecular attractions.
• 3. molecules of gases are kind of like soft spheres and when they change shape which takes more time.

it states that when measured at the same temperature and  pressure, volumes of gaseous reactants and products of chemical reactions are in simple ratios of whole numbers.

as pressure on a gas increases, volume of a gas decreases.

as temperature increases pressure increases porportionally.

shows the interelationship between chemical amount, temperature, pressure and volume.

states that the products of the pressure and volume of a gas sample is porportional to its absolute temperature in kelvin.

• provides a scientific model for explaining the behavior of gases.
• states that
• 1. ideal gases are hypothetical gases that obey all gas laws perfectly under any condition.
• 2. real gases are nearly similar to ideal gases at low temperatures and high pressure but deviate under certain conditions.

law of combining volumes.

equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
