JEE MAIN - Physics (2024 - 30th January Evening Shift - No. 5)
Choose the correct statement for processes A & B shown in figure.
_30th_January_Evening_Shift_en_5_1.png)
$$P V=k$$ for process $$B$$ and $$A$$.
$$\frac{P^{\gamma-1}}{T^\gamma}=k$$ for process $$B$$ and $$T=k$$ for process $$A$$.
$$\frac{T^\gamma}{P^{\gamma-1}}=k$$ for process $$A$$ and $$P V=k$$ for process $$B$$.
$$P V^{\prime}=k$$ for process $$B$$ and $$P V=k$$ for process $$A$$.
Explanation
Steeper curve (B) is adiabatic
Adiabatic $$\Rightarrow \mathrm{PV}^v=$$ const.
Or $$\mathrm{P}\left(\frac{\mathrm{T}}{\mathrm{P}}\right)^v=$$ const.
$$\frac{\mathrm{T}^v}{\mathrm{P}^{v-1}}=\text { const. }$$
Curve (A) is isothermal
$$\mathrm{T}=$$ const.
$$\mathrm{PV}=$$ const.
