Question

Types of system and their definitions are given below. Choose the correct match from the following codes:
System:
(a) Closed system
(b) Open system
(c) Isolated system
(d) Homogeneous system
(e) Heterogeneous system
Definition:
(i) A system which can exchange both energy and matter with surrounding
(ii) A system which cannot exchange matter or energy with surrounding
(iii) A system consisting of single phase
(iv) A system consisting of many phases
(v) A system which can exchange only energy with surrounding

• A. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv), (e)-(v)
• B. (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv), (e)-(v)
• C. (a)-(i), (b)-(ii), (c)-(iv), (d)-(iv), (e)-(iii)
• D. (a)-(v), (b)-(i), (c)-(ii), (d)-(iii), (e)-(iv)
• E. (a)-(v), (b)-(ii), (c)-(i), (d)-(iii), (e)-(iv)

Hint:

Remember: Open → energy + matter exchange, Closed → only energy exchange, Isolated → no exchange. Homogeneous → single phase, Heterogeneous → multiple phases.

Answer 1

The Correct Option is D

Step 1: Understand the concept of different types of thermodynamic systems.
In thermodynamics, systems are classified based on their ability to exchange energy and matter with the surroundings. Additionally, systems can be classified based on phases present.

Step 2: Define a closed system.
A closed system can exchange only energy (like heat or work) with surroundings but not matter. Therefore, closed system corresponds to:
\[ (a) \rightarrow (v) \]

Step 3: Define an open system.
An open system can exchange both energy and matter with surroundings. Hence:
\[ (b) \rightarrow (i) \]

Step 4: Define an isolated system.
An isolated system cannot exchange either energy or matter with surroundings. Therefore:
\[ (c) \rightarrow (ii) \]

Step 5: Define a homogeneous system.
A homogeneous system consists of only one phase and has uniform composition throughout. Thus:
\[ (d) \rightarrow (iii) \]

Step 6: Define a heterogeneous system.
A heterogeneous system consists of two or more phases and has non-uniform composition. Hence:
\[ (e) \rightarrow (iv) \]

Step 7: Combine all matches and select the correct option.
Putting all together: \[ (a)-(v),\ (b)-(i),\ (c)-(ii),\ (d)-(iii),\ (e)-(iv) \] This corresponds to option \((4)\).
