Question

Air contained in a rigid, insulated tank fitted with a paddle wheel, initially at 300 K, 2 bar, and a volume of 2 m3, is stirred until its temperature is 500 K. Assuming the ideal gas model, for the air, and ignoring kinetic and potential energy, determine

Answer 1

The final pressure in bar will be "
`(10)/(3) \ Bar`".

Step-by-step explanation:

As we know,

PV = nRT

`(P_1)/(T_1) =(P_2)/(T_2) =CONST`

then,

⇒
`(2 \ bar)/(300 \ K) = (P_2)/(500 \ K)`

⇒
`P_2=((2)/(300)* 500 )Bar`

`=(10)/(3) \ Bar`

Thus the above is the correct answer.
