Test: Basic Concept - 3 - Question 8

Match the List-I (Terms) with List-ll (Description) and select the correct answer:

List-I
A. Change of state
B. Path
C. Process

List-ll
1. Succession of states
2. One or more properties changes
3. Change of state for specified path

Detailed Solution for Test: Basic Concept - 3 - Question 8

Properties are the coordinates to describe the state of a system. They are state variables of the system. Any operation in which one or more of the properties of a system changes is called a change of state. The succession of states passes through during a change of state is called the path of the change of state is called a process. A thermodynamic cycle is defined as a series of state changes such that the final state is identical with the initial state.

1. no heat transfer takes place
2. no work is done
3. no mass crosses the boundary
4. no chemical reaction takes place within the system
