What are thermodynamic processes?
(N/A) Thermodynamic processes are defined as follows:
$(1)$ Isothermal process: The process during which the temperature of the system remains constant.
$(2)$ Isobaric process: The process during which the pressure of the system remains constant.
$(3)$ Isochoric process: The process during which the volume of the system remains constant.
$(4)$ Adiabatic process: $A$ process in which a system undergoes physical changes such that no heat is exchanged between the system and its surroundings $(\Delta Q = 0)$.
$(5)$ Cyclic process: $A$ process in which a system undergoes a series of changes that return the system back to its initial state.
Some special thermodynamic processes are summarized in the table below:
$(1)$ Isothermal process: The process during which the temperature of the system remains constant.
$(2)$ Isobaric process: The process during which the pressure of the system remains constant.
$(3)$ Isochoric process: The process during which the volume of the system remains constant.
$(4)$ Adiabatic process: $A$ process in which a system undergoes physical changes such that no heat is exchanged between the system and its surroundings $(\Delta Q = 0)$.
$(5)$ Cyclic process: $A$ process in which a system undergoes a series of changes that return the system back to its initial state.
Some special thermodynamic processes are summarized in the table below:
| Type of process | Feature |
| Isothermal | Temperature constant |
| Isobaric | Pressure constant |
| Isochoric | Volume constant |
| Adiabatic | No heat flow $(\Delta Q = 0)$ |

View SolutionThe efficiency of the cycle shown in the figure (consisting of one isobar,one adiabat,and one isotherm) is $50 \%$. The ratio $x$ between the highest and lowest temperatures attained in this cycle obeys (the working substance is an ideal gas):
One mole of an ideal gas at initial temperature $T$ undergoes a quasi-static process during which the volume $V$ is doubled. During the process,the internal energy $U$ obeys the equation $U = a V^3$,where $a$ is a constant. The work done during this process is
