During an experiment an ideal gas is found to obey a condition P^2 = constant ( = density of gas). The gas is initially at temperature T₀ , pressure P₀ and density ₀ . The gas expands such that density changes to ₀ 2 . Then which of the following is/are correct:

Options

  1. AThe pressure of the gas changes to 2 P ₀
  2. BThe temperature of the gas changes to 2 ~T ₀
  3. CThe graph of the above process on the P - T diagram is parabola.
  4. DThe graph of the above process on the P - T diagram is hyperbola.

Correct answer

D. The graph of the above process on the P - T diagram is hyperbola.

Step-by-step solution

P ^2 = constant P^2(n R T) M P = constant PT = constant
