Answer to Question #61123 in Physical Chemistry for Amit Sharma

Question

Define the following terms:
i) Isolated system
ii) Isothermal process
iii) Adiabatic process
iv) Isobaric process
v) Isochoric process

Answer 1

Answer:
i) Isolated system
In physical science, an isolated system is either of the following:
1. a physical system so far removed from other systems that it does not interact with them.
2. a thermodynamic system enclosed by rigid immovable walls through which neither matter nor energy can pass.

ii) Isothermal process
An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0.
iii) Adiabatic process
An adiabatic process is one that occurs without transfer of heat or matter between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred only as work.
iv) Isobaric process
Isobaric process
v) Isochoric process
An isochoric process, also called a constant-volume process, an isovolumetric process, or an isometric process, is a thermodynamic process during which the volume of the closed system undergoing such a process remains constant.
