Short Answer Type
Long Answer TypeWhat do you understand by:
(i) Isothermal process
(ii) Adiabatic process
(iii) Isobaric process
(iv) Isochoric process
(v) Cyclic process?
(i) Isothermal process: A process is said to be isothermal if the temperature of the system remains constant i.e. operation is carried at a constant temperature. For an isothermal process, dT = 0 where dT is the change in temperature.
(ii) Adiabatic process: In an adiabatic process, no heat can flow from the system to the surrounding or vice versa i.e. the system is completely insulated from the surroundings.
(iii) Isobaric process: It is the process during which the pressure of the system is kept constant i.e. dP = 0. The volume may or may not change.
(iv) Isochoric process: It is a process during which the volume of the system is kept constant i.e dV = 0.
(v) Cyclic process. When a system undergoes a series of changes and finally returns to its initial state, it is an example of the cyclic process. In cyclic process dU = 0.
Short Answer TypeClassify the following processes as reversible or irreversible:
(i) mixing of two gases by diffusion.
(ii) dissolution of sodium chloride in water
(iii) evaporation of water at 373 K at 1 atm pressure
(iv) expansion of a gas in vacuum.
