what is the difference between ideal and perfect gas?

Perfect gas is the gas that have intermolecular attraction zero. ... Ideal gas are some what similar to perfect gas ,they obeys gas laws. And the only difference is specific heat is a function of temperature. And at high temperatures and low pressure real gases acts like ideal gas .

The atoms and molecules in gases are much more spread out than in solids or liquids. ... A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

At constant temperature and pressure the volume of a gas is directly proportional to the number of moles of gas. At constant temperature and volume the pressure of a gas is directly proportional to the number of moles of gas. Or you could think about the problem a bit and use PV=nRT. N2O is placed in a piston.

An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. ... In such a gas, all the internal energy is in the form of kinetic energy and any change in internal energy is accompanied by a change in temperature.

Freespace would be the absence of all mass (i.e. in a volume with a density of exactly zero), whereas "vacuum" only implies a sub-atmospheric density. The "power" of the vacuum is usually given in terms of pressure, which is easily converted to density using the ideal gas equation of state.

Explanation: Boyle's Law tells us that for an ideal gas, at a constant temperature, volume is proportional to pressure. ... Charles' Law tells us that for an ideal gas, at constant pressure, volume is proportional to temperature (where temperature is in degrees Kelvin).

solid: Has a definite shape and volume. liquid: Has a definite volume, but take the shape of the container. gas: Has no definite shape or volume.

An ideal gas has identical particles of zero volume, with no intermolecular forces between them. The atoms or molecules in an ideal gas move at the same speed. ... When pressures are very high and the molecules are compressed, the volume of the molecules becomes significant.

A gas, on the other hand, has a vol- ume that changes to match the volume of its container. The molecules in a gas are very far apart compared with the molecules in a solid or a liquid. The amount of space between the molecules in a gas can change easily.

Air is a solution of gases. A vacuum is simply space which has sub-atmospheric pressure.

The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape. Gas can be compressed much more easily than a liquid or solid.

Specific Heat for an Ideal Gas at Constant Pressure and Volume. This represents the dimensionless heat capacity at constant volume; it is generally a function of temperature due to intermolecular forces. For moderate temperatures, the constant for a monoatomic gas is cv=3/2 while for a diatomic gas it is cv=5/2 (see ).

Why is real gas approximated to ideal gas at low density? - Quora. Why is real gas approximated to ideal gas at low density? ... Ideal gases have zero intermolecular forces. In many real gases, intermolecular forces are very small.

A gas does not have a definite mass. ... A gas does not have a definite volume. A gas does not always weigh the same or take up the same amount of space. However, like a liquid, a gas will always take the shape of its container, no matter the size or shape of that container.

Thus, in an isothermal process the internal energy of an ideal gas is constant. ... In the isothermal compression of a gas there is work done on the system to decrease the volume and increase the pressure. Doing work on the gas increases the internal energy and will tend to increase the temperature.

Ideal solutions are uniform mixtures of components that have physical properties connected to their pure components. ... So an azeotrope can be defined as a solution whose vapor has the same composition its liquid.
