Which law relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions?
Elanso [62]

Ideal gas law

Explanation:

The ideal gas law relates the temperature, pressure, volume and the number of moles of a gas under perfect conditions.

The ideal gas law is a combination of:

    Boyle's law- "the volume of a fixed mass of gas varies inversely as the pressure changes if the temperature is constant"

   Charles's law - "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant"

    Avogadro's law - "equal volumes of all gases at the same temperature and pressure contains equal number of molecules".

 The law gives:

                     PV = nRT

where:

   P is the pressure of the gas

   V is the volume of gas

    n is the number of moles

     T is the temperature

     R is the gas constant

What are the laws and calculations governing gas behavior?
Thepotemich [5.8K]

Answer:

Laws governing gas behavior.

Explanation:

Boyle's law:

It relates the pressure and volume of an ideal gas at a constant temperature.

According to this law:

"The volume of a fixed amount of gas at constant temperature is inversely proportional to its pressure".

P  \alpha   V.

Charle's law:

It relates the volume and absolute temperature of an ideal gas at a constant pressure.

According to this law:

"The volume of a fixed amount of gas at constant pressure is directly proportional to its absolute temperature".

V   \alpha   T.

Avogadro's law:

According to this law:

equal volumes of all gases under the same conditions of temperature and pressure contain, an equal number of moles.

V   \alpha    n.

Ideal gas equation:

By combining all the above-stated gas laws, this equation is formed as shown below:

V  \alpha   \frac{nT}{P} \\=> V= R. nT/ P\\=>PV=nRT

R is called universal gas constant.

It has a value of 0.0821L.atm.mol-1.K-1.
