A 1m3 tank containing air at 25℃ and 500kPa is connected through a valve to
Aliun [14]

Answer:

The right answer is "2.2099 m³".

Explanation:

Given:

Mass,

m = 5 kg

Temperature,

T = 35℃

or,

  = 35 + 273

Pressure,

P = 200 kPa

Gas constant,

R = 0.2870 kj/kgK

By using the ideal gas equation,

The volume will be:

⇒ PV=mRT

or,

⇒    V=\frac{mRT}{P}

By substituting the values, we get

          =\frac{5(0.2870)(35+273)}{200}

          =\frac{441.98}{200}

          =2.2099 \ m^3
