Question 995: Thermodynamics & KTG

Question

Two different ideal diatomic gases $A$ and $B$ are initially in the same state. $A$ and $B$ are then expanded to same final volume through adiabatic and isothermal process, respectively. If $p_A, p_B$ and $T_A, T_B$ represent the final pressures and temperatures at $A$ and $B$ respectively, then

Accepted Answer

In adiabatic process, pressure will be less. Further temperature is the product of $p$ and $V$, hence $p_A< p_B$ and $T_A< T_B$.

Answer

$p_A< p_B$ and $T_A< T_B$

Answer

$p_A>p_B$ and $T_A>T_B$

Answer

$p_A>p_B$ and $T_A< T_B$

Answer

$p_A< p_B$ and $T_A>T_B$
