For the given cycle, the work done during isobaric process is:

Figure below shows two paths that may be taken by a gas to go from a state A to a state C. In process AB, 400 J of heat is added to the system and in process BC, 100 J of heat is added to the system. The heat absorbed…

An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric and isochoric. The curve which represents the adiabatic…

Thermodynamic processes are indicated in the following diagram. Match the following Column - 1 Column - 2 P. Process I a. Adiabatic Q. Process II b. Isobaric R. Process III c. Isochoric S. Process IV d. Isothermal

One mole of an ideal diatomic gas undergoes a transition from $A$ to $B$ along a path $\mathrm{AB}$ as shown in the figure, The change in internal energy of the gas during the transition is:

A thermodynamics system undergoes cyclic process $ABCDA$ as shown in Figure. The work done by the system in the cycle is:

In the reported figure, there is a cyclic process $ABCDA$on a sample of $1$ mol of a diatomic gas. The temperature of the gas during the process $A\rightarrow\,B$ and $C\rightarrow\,D$ are $T_{1}$ and…

An ideal gas goes through a reversible cycle $a\rightarrow\,b\rightarrow\,c\rightarrow\,d$ has the V - T diagram shown below. Process $d\rightarrow\,aandb\rightarrow\,c$ are adiabatic. The corresponding P - V diagram…

$n$moles of an ideal gas undergoes a process $A\rightarrow\,B$ as shown in the figure. The maximum temperature of the gas during the process will be:

In $1^{\mathrm{st}}$ case, Carnot engine operates between temperatures $300 K$ and $100 K$. In $2^{\mathrm{nd}}$ case, as shown in the figure, a combination of two engines is used. The efficiency of this combination (in…

$n$mole of a perfect gas undergoes a cyclic process $ABCA$(see figure) consisting of the following processes. $A\rightarrow\,B:$ Isothermal expansion at temperature $T$ so that the volume is doubled from $V_{1}$ to…

A certain gas is isothermally compressed to $\left(\dfrac{1}{3}\right)^{rd}$ of its initial volume ($V_o = 3$ litre) by applying required pressure. If the bulk modulus of the gas is $3 \times 10^5$ N/m$^2$, the…
