Class 11PhysicsKinetic Theory of GasesGas Laws (Charles, Boyle's, Avagadro's, Gay Lussacs and Dalton's law) and Ideal gas Equation
MediumFor an ideal gas,the density of the gas is $\rho_0$ when the temperature and pressure of the gas are $T_0$ and $P_0$ respectively. When the temperature of the gas is $2 T_0$,its pressure becomes $3 P_0$. The new density will be:
- A$\frac{3}{2} \rho_0$
- B$\frac{4}{3} \rho_0$
- C$\frac{3}{4} \rho_0$
- D$\frac{2}{3} \rho_0$
