**Properties of substances in thermodynamic coordinates**
Properties of substances in thermodynamic coordinates, such as pressure, temperature, and density, can be classified as either path functions or point functions. In this case, the correct answer is option 'B' - point functions.
**Path functions**
Path functions are properties that depend on the path taken to reach a particular state or condition. These properties are typically associated with the transfer of energy or work. Examples of path functions in thermodynamics include heat transfer and work done on or by a system.
For example, the amount of heat transferred to a substance during a heating process depends on the specific path taken. Similarly, the work done on a gas during compression depends on the specific steps taken to reach the final state. Path functions are not solely determined by the initial and final states of a system but also depend on the process or path followed.
**Point functions**
In contrast, point functions are properties that depend only on the current state or condition of a system and are independent of the path taken to reach that state. These properties have a unique value for a given state and are not affected by the history of the system. Pressure, temperature, and density are examples of point functions.
Regardless of the path or process used to achieve a specific pressure, temperature, or density, these properties will have the same value if the system is in the same state. For instance, if a gas is at a pressure of 1 bar, it does not matter how the gas was brought to that pressure; the value of pressure will be the same. Similarly, the temperature of a substance will remain constant as long as the state of the substance remains unchanged, regardless of the path taken to reach that state.
**Conclusion**
In summary, properties of substances such as pressure, temperature, and density in thermodynamic coordinates are considered point functions. These properties depend only on the current state of a system and are independent of the path taken to reach that state.
