Embibe Experts Solutions for Chapter: Thermodynamics, Exercise 1: Exercise 1

If system $A$ is in thermal equilibrium with $B$ and $B$ is separately in thermal equilibrium with $C,$ then $A$ and $C$ are in thermal equilibrium. From which thermodynamics law, does this follow?

A thermodynamic system is taken through the cycle $ABCD$ as shown in the figure. Heat rejected by the gas during the cycle is:

A gas mixture consists of 2 moles of oxygen and 4 moles of argon at temperature T. Neglecting all vibrational modes, the total internal energy of the system is:

The volume $\left(V\right)$ of a monatomic gas varies with its temperature $\left(T\right)$ as shown in the graph. The ratio of work done by the gas to the heat absorbed by it, when it undergoes a change from state $A$ to state $B$ is?

$C_{\mathrm{P}}$ and $C_{\mathrm{V}}$ are specific heats at constant pressure and constant volume, respectively. It is observed that $C_{\mathrm{P}}-C_{\mathrm{V}}=a$ for hydrogen gas, $C_{\mathrm{P}}-C_{\mathrm{V}}=b$ for nitrogen gas. The correct relation between $a$ and $b$ is

Thermodynaic processes are indicated in the following diagram:

A gas with the ratio of specific heat $y$ expands from an initial pressure of $p_1$ and volume $V_1$ to pressure $p_2$ and volume $V_2\text{,}$ adiabatically. The work done is given by

The net amount of the work done in the following indicator diagram is -
