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.

How does change in pressure affect ratio of PV to nRT in real gases?
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.
What happens to the pressure of a sample gas if you double the volume and no change in the Kelvin temperature?
pV = nRT ← General Gas Lawrearranging to solve the pressure gives us:p = nRT/Vdoubling the volume gives: p = nRT/2VThis means that the pressure will be halved.

What affect the pressure of a gas?
The ideal gas law could be written to say the P = nRt/v. So gas pressure, P, is affected by n, the number of gas molecules; t, temperature; and v, volume. "R" is a natural constant.
What is one of the following equations encompasses Boyle's Law Charles Law and the relationship between pressure and temperature when the volume is constant?
The ideal gas law, PV=nRT, combines Boyle's Law (P1V1 = P2V2), Charles's Law (V1/T1 = V2/T2), and relates the pressure and temperature of a gas when the volume is held constant.
Is it gas compression ratio is more in tertiary of cretaceous?
Because in tertiary temprature is high so pressure is high as( PV=nRT)

There are 2 grams of H2 gas in a fixed volume container at 273 C. 16 grams of He gas isadded to the container and the temperature is raised to 819 C. So what is the ratio of finalpressure to initial pressure?
The ideal gas law, (PV = nRT), can be used here. The initial pressure is proportional to the initial number of moles, and the final pressure is proportional to the total number of moles. Therefore, the ratio of final pressure to initial pressure is the ratio of the total number of moles of gas at the final conditions to the number of moles initially in the container.
What is the formula for calculating the change in pressure when the volume and temperature of a gas are held constant?
The formula for calculating the change in pressure when the volume and temperature of a gas are held constant is: P (nRT/V)T, where P is the change in pressure, n is the number of moles of gas, R is the gas constant, T is the temperature, V is the volume, and T is the change in temperature.
How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.

What volume will 1.25 liters of carbon dioxide occupy at 50.0 degrees if the pressure changes from 0.865 ATM to 0.820 ATM?
Using the ideal gas law (PV = nRT), you can calculate the initial and final number of moles of CO2. Given that the temperature remains constant, the ratio of the initial volume to final volume is equal to the ratio of the initial pressure to the final pressure. Applying this ratio to the initial volume of 1.25 liters will give you the final volume.
