What is the physical significance of the constancy of the various values of PV?
The constancy of the value of the product of pressure and volume for a closed system (PV) at constant temperature is useful in establishing a definition of temperature and allows the extrapolation of the temperature scale to a thermodynamic "absolute zero".
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?
inversely proportional
How do you find the temperature if pressure is kept constant?
PV=nRt. If P is constant, get the value of V and solve for t.
Which law relates the quantities of pressure volume temperature and quantity of moles?
This is the combined gas law: pV=nRT.
How does the changes in temperature and pressure affect the volume and the amount of gases?
In general chemistry we are taught the ideal gas equation of state PV=nRT. n is the number of moles of gas and R is the molar gas constant. This is an extremely important equation in the study of thermodynamics.
Does changing the temperature of a gas has no effect on the volume of the gas?
No, it does affect the volume of a gas according to the ideal gas law (PV=nRT).
What is an expression of Boyle's law?
PV = constant
If you increase the temperature of an object does it affect the volume?
Yes, it does affect the volume. The relationship between them can be explained by the equation pV=nRT (pressure x volume = number of moles of gas x molar gas constant x temperature). Therefore, there is a direct proportionality between temperature and volume. If the temperature doubles, so does the volume.

Describe the relationship between the pressure of gas and temperature?
PV=nRT
Why should temperature be in kelvin in the equation pV equals nRT?
Most other temperature scales are not absolute - the lowest possible temperature is not zero.
State the ideal gas law?
PV=nRT D:
What would be the pressure in mm Hg if this gas was allowed to expand to 975 ml at a constant temperature?
This cannot be answered without an initial volume or pressure. But the final pressure of an expansion of a gas can be determined by the following formula. PV/T = P'V'/T' where P = pressure absolute V = volume T = temperature absolute ( ' ) indicates the new pressure, volume and temperature because the temperature is constant this can be reduced to PV = P'V' or P' = PV/V'
What does the area enclosed by a PV diagram and TS diagram show?
Area enclosed by the PV (pressure-volume) and TS (temperature-entropy) diagrams shows the work done by the system.
Why does the pressure of a gas at constant temperature decrease when the volume of the gas is decreased?
This is a consequence of Boyle-Mariotte law: pV=k. at constant temperature.
How do you Calculate the molar volume of a gas?
use pv=nrt, where p = pressure , v = volume, n=moles, r is a constant (8.413372) and t is the temperature. you can also use pv/t = pv/t where one side is stp (standard temperature and pressure) and the other side is your information with one variable left over, in your case volume, that you then calculate.
