Question

what is system,boundary and surroundings?

Answer 1

averages properties, energy levels, and probabilities of individual molecules Page 5 5 System, Surrounding andBoundary A system is a region containing energy and/or matter that is separated from its surroundings by arbitrarily imposed walls orboundaries.

Answer 2

Answer:

(1) System: The portion of the universe under thermodynamic consideration to study thermodynamic propertics is called a sysiem.

Explanation :

As such any portion of the universe under thermodynamic consideration is a system. The thermodynamic consideration involves the Study of thermodynamic parameters like pressure, volume, temperaure, energy, tc.

(1) The system may be very small or very large.

(2) The system is confined by a real or an imaginary boundary.

(2) Surroundings : 1he remaining portion of the universe other than under thermodynamics study

1.e., the system is called the surroundings.

Explanation

1) Suroundings represent a large stock of mass and energy and can be exchanged with the system when allowed.

(2) For a liquid in an open vessel, the surrounding atmosphere around it represents the surroundings.

(3) Boundary : The wall or interface separating the system from its surrounding is called a boundary.

Explanation

(1) This boundary may be either real or imaginary.

2) Through this boundary, exchange of heat and matter between the system and surroundingsncan take place, e.g. when a liquid is placed in anbeaker the walls of beaker represent realnboundaries while open portion of the beaker is imaginary boundary.

i) Evcrything outside the boundary representsnsurroundings.
