Question

According to Kinetic theory of gas, what is the pressure of an ideal gas molecule ?​

Answer 1

Kinetic Theory of Ideal Gases:-

• An ideal gas is a gas where the atoms do not exert forces on each other but they do collide with the walls of the container (in elastic collisions).

• PV=nRT.

where,

P= pressure of the gas (pascal)

V= volume of gas (litres)

n= number of moles of gas (moles)

R= universal or ideal gas constant (=8.314JK-1mol-1)

Answer 2

According to the Kinetic theory of gas, the pressure of an ideal gas molecule is, $P = \frac{nRT}{V}$.

• The equation of state of an ideal gas is given as,

        $PV = nRT$

• Here, P is the pressure, V is the volume, T is the absolute temperature and n is the number of moles of the ideal gas.
• R is the molar gas constant whose value is equal to 8.315 J mol⁻¹ K⁻¹.
• On rearranging the given equation, P is given by,

        $P = \frac{nRT}{V}$
