Question

Which of the following graphs is not correct for ideal gas?

Options

• 

  [d = density, P = pressure, T = Temperature]

• 

  [d = density, P = pressure, T = Temperature]

• 

  [d = density, P = pressure, T = Temperature]

• 

  [d = density, P = pressure, T = Temperature]

Answer 1

[d = density, P = pressure, T = Temperature]

Explanation:

From the ideal gas equation, we get,

PM = dRT

⇒ d = `["PM"/"R"]1/"T"`

So graph d vs T is not a straight line.
