Draw $P-V$ curves for isothermal and adiabatic processes of an ideal gas.
(N/A) The $P-V$ diagram represents a Carnot cycle,which consists of two isothermal processes and two adiabatic processes.
$1$. Isothermal expansion: The gas expands at a constant temperature.
$2$. Adiabatic expansion: The gas expands without any heat exchange with the surroundings.
$3$. Isothermal compression: The gas is compressed at a constant temperature.
$4$. Adiabatic compression: The gas is compressed without any heat exchange with the surroundings.
The adiabatic curves are steeper than the isothermal curves because the adiabatic bulk modulus is $\gamma$ times the isothermal bulk modulus,where $\gamma > 1$.

View SolutionAn ideal gas undergoes a cyclic process through various thermodynamic states. The heat energy $(Q)$ and work $(W)$ associated with these states are given as follows:
$Q_1 = 6000 \ J, Q_2 = -5500 \ J, Q_3 = -3300 \ J, Q_4 = 3500 \ J,$
$W_1 = 2500 \ J, W_2 = -1000 \ J, W_3 = -1200 \ J, W_4 = x \ J$
If the ratio of the net work done to the net heat absorbed is $\eta$, then the values of $x$ and $\eta$ are respectively:
$Q_1 = 6000 \ J, Q_2 = -5500 \ J, Q_3 = -3300 \ J, Q_4 = 3500 \ J,$
