During an experiment, an ideal gas is found to obey a condition P2ρ=\frac{P^2}{\rho}= constan tt, ( ρ=\rho= density of the gas). The gas is initially at temperature T, pressure P\mathrm{P} and density ρ\rho. The gas expands such that density changes to ρ/2\rho / 2. Then,
View answer and explanation
Correct option: D
The graph of the above process on P\mathrm{P} - T\mathrm{T} diagram is hyperbola.
Option D is correct because the process follows PT = constant, which represents a hyperbola on the P-T diagram.
