Question

If critical temperature (Tc) and critical pressure (Pc) of one mole of gas are 700K and 62 atm , then the value of critical volume (Vc) is

Answer 1

Answer:

Critical volume = 0.0009264 m^3.

Explanation:

Since we know the ideal gas equation for n mole

$PV = nRT$........................................(1)

Assume n = 1 mole.

Where P = Pressure , V = Volume , n= no. of moles , T = temperature , R= gas constant = 8.314 j/kg k

P = 62 x  101325 pascal = 6282150 pascal

Apply equation (1) we get

6282150 x V = 1 x 8.314 x 700

So, Critical volume = 0.0009264 m^3.

Answer 2

Thus the Critical volume = 0.0009264 m^3.

Explanation:

Since we know the ideal gas equation for n mole ...(1)

Assume n = 1 mole.

Where P = Pressure , V = Volume , n= no. of moles , T = temperature , R= gas constant = 8.314 j/kg k

P = 62 x  101325 pascal = 6282150 pascal

Apply equation (1) we get

6282150 x V = 1 x 8.314 x 700

So, Critical volume = 0.0009264 m^3.
