In real gases, the ratio ( \frac{PV}{nRT} ) deviates from 1 due to intermolecular forces and finite molecular volumes. As pressure increases, the volume of the gas decreases, and the effects of these interactions become more pronounced, causing ( \frac{PV}{nRT} ) to deviate further from ideal behavior. At high pressures, this ratio typically drops below 1 due to repulsive forces and reduced volume, while at low pressures, it may approach or exceed 1 as gas molecules behave more ideally. Thus, pressure changes significantly influence the behavior of real gases compared to the ideal gas law.

How does a change in pressure affect the ratio of PV to nRT?
A change in pressure does not affect the ratio of PV to nRT. The ideal gas law equation (PV = nRT) represents a constant relationship between pressure (P), volume (V), number of moles (n), gas constant (R), and temperature (T). Any change in pressure will lead to a corresponding change in volume, temperature, or number of moles to maintain the relationship defined by the ideal gas law.
What back pressure in gas turbine?
Back pressure in a gas turbine refers to the resistance against the flow of exhaust gases as they exit the turbine. It can affect the turbine's efficiency and performance, as higher back pressure can reduce the effective pressure ratio and limit the engine's output power. Proper management of back pressure is essential for optimizing gas turbine operation, particularly in applications like power generation and aviation. Factors influencing back pressure include exhaust duct design, atmospheric conditions, and the presence of any obstructions or restrictions in the exhaust path.
Why would a test tube volume ratio match subscripts of a product?
A test tube volume ratio matching the subscripts of a product indicates that the gases involved in the reaction behave ideally and occupy volumes directly proportional to their mole ratios. According to Avogadro's law, equal volumes of gases at the same temperature and pressure contain an equal number of molecules. Therefore, if the reaction produces gases, the volume ratios of the products will reflect the stoichiometric coefficients (subscripts) of the balanced chemical equation. This relationship simplifies predicting the volumes of gases formed from given reactant amounts in a chemical reaction.
Are gases soluble in one another?
Yes, but this is NOT called 'solubility' but mixing at any ratio of ALLgases
What is Gay-Lussac's law of combining volumes?
Gay-Lussac's Law states that the pressure of a sample of gas at constant volume, is directly proportional to its temperature in Kelvin. The P's represent pressure, while the T's represent temperature in Kelvin. P1 / T1 = constant After the change in pressure and temperature, P2 / T2 = constant Combine the two equations: P1 / T1 = P2 / T2 When any three of the four quantities in the equation are known, the fourth can be calculated. For example, we've known P1, T1 and P2, the T2 can be: T2 = P2 x T1 / P1
How does a change in pressure affect the ratio of PV to nRT?
A change in pressure does not affect the ratio of PV to nRT. The ideal gas law equation (PV = nRT) represents a constant relationship between pressure (P), volume (V), number of moles (n), gas constant (R), and temperature (T). Any change in pressure will lead to a corresponding change in volume, temperature, or number of moles to maintain the relationship defined by the ideal gas law.
When two gases of a chemical reaction are both at the same temperature and pressure and they have the same molar volume what is their stoichiometric ratio in the chemical equation describing the reac?
If the gases have the same molar volume, the stoichiometric ratio would be one to one. Molar volume is the volume occupied by one mole of a substance. This indicates that there is a 1:1 molar ratio of each gas.
What is the relationship between the stagnation pressure ratio across a normal shock and the resulting flow stagnation pressure?
The stagnation pressure ratio across a normal shock is directly related to the resulting flow stagnation pressure. As the stagnation pressure ratio increases, the flow stagnation pressure also increases. This relationship helps to understand how shocks affect the pressure in a flow.
What is the significance of the cp/cv ratio in thermodynamics and how does it affect the behavior of gases?
The cp/cv ratio in thermodynamics is important because it helps determine how gases behave when heated or cooled. Specifically, it affects how much a gas's temperature changes when it absorbs or releases heat. Gases with a higher cp/cv ratio tend to experience larger temperature changes for the same amount of heat added or removed, while gases with a lower ratio have smaller temperature changes. This ratio is crucial in understanding and predicting the behavior of gases in various thermodynamic processes.
Define leverage ratio?
Leverage Ratio is an idea of how a change in a company's output will affect their operating income. It is used to measure a company's mix of operating costs, showing how a change in the company's ideas will affect the output of their operating income.
Is pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
What is jet engine engine pressure ratio?
The pressure ratio in jet engines is the ratio of pressure between the entrance of the compressor and the exit of the compressor.
What is Gay-lussac?
A law stating that the volumes of gases undergoing a reaction at constant pressure and temperature are in a simple ratio to each other and to that of the product.Gay-Lussac's law, known as the law of combining volumes, states that: The ratio between the combining volumes of gases and the product, if gaseous, can be expressed in small whole numbers
Does tire size affect gear ratio?
It does affect overall ratio. The transmission ratios, the axle ratio, and tire size all figure into overall ratio.
What is compression ratio in air compressor?
The compression ratio is simply the ratio of the absolute stage discharge pressure to the absolute stage suction pressure.
