Answer
a- Property, b- State, c- Process, d- Property, e- State, f- Property, g- Property
Work Step by Step
Property- a,d,f,g
Property is a special quality or characteristic of something, and to which a numerical value can be assigned. Examples are pressure, volume, mass, energy etc
State- b,e
State is the particular condition that someone or something is in at a specific time. The state of a system is defined with the help of its properties. Points b and e describe the pressure and specific volume of the system, hence are two states.
Process- c
The path which connects two states of a system is called a process. Process involves the change in state and therefore, the properties of a system. Thus the line joining 1 and 2 is a process.
