A path function is one where it the value of the function depends on the path you took from the initial and final state. Work and Heat are path functions.
A "point function" is one that only has points as values rather than being continuous. The only point functions in thermodynamics are where the thermodynamic conditions are fully constrained - such as pure component triple points and critical points. At the triple point vapor, liquid, and solid can coexist in equilibrium. That only happens at a single temperature and pressure. Likewise, the critical point only occurs at the critical temperature and pressure. If you have a mixture, you get a continuous function over a composition range rather than a single point.
If by "point function" the questioner meant to refer to those functions/properties where the value only depends on the point where you start and the point where you end, the correct name is "state function". In thermodynamics changes in internal energy, enthalpy, Helmoltz energy, and Gibbs free energy depend only on starting and ending conditions and are State Functions.

What is path function in thermodynamics?
A path function in thermodynamics is a function whose value depends on the path taken to reach a particular state. Examples include work and heat. These functions are not solely determined by the initial and final states but also by the process followed.
Which law states that internal energy is function of Temperature?
The First Law of Thermodynamics states that the internal energy of a system is a function of temperature. It describes the relationship between heat transfer, work done, and changes in internal energy. It is a fundamental principle in the field of thermodynamics.
What is microscopic and macroscopic view point in thermodynamics?
Microscopic viewpoint in thermodynamics focuses on individual molecules and their interactions, while macroscopic viewpoint looks at bulk properties of a system, such as temperature and pressure. These viewpoints help to describe and analyze the behavior of systems at different scales.
Is thermodynamics the same as physical chemistry?
Thermodynamics is considered a part of physical chemistry.
What is the study of conversion of heat to mechanics?
The study of converting heat into mechanical energy is called thermodynamics. It is a branch of physics that deals with the relationships between heat, work, and energy. Thermodynamics is essential for understanding and optimizing processes such as engines, refrigeration, and power generation.
Is pressure a state function in thermodynamics?
No, pressure is not a state function in thermodynamics.
Is work a state function in thermodynamics?
No, work is not a state function in thermodynamics.
Define point function and path function?
A point function is a function whose value depends only on the state of a system at a single point, regardless of the path taken to reach that state. Examples include pressure, temperature, and density. In contrast, a path function depends on the path taken to reach a particular state and not just the initial and final states of a system. Examples include work and heat.
What is the significance of the state function in thermodynamics?
In thermodynamics, a state function is significant because it only depends on the current state of a system, not how it got there. This allows for easier analysis and calculation of properties like energy, pressure, and temperature.
What is a state function and how is it best described in thermodynamics?
A state function is a property of a system that depends only on its current state, not on how it got there. In thermodynamics, it is best described as a function that is independent of the path taken to reach a particular state. Examples include temperature, pressure, and internal energy.
What is path function in thermodynamics?
A path function in thermodynamics is a function whose value depends on the path taken to reach a particular state. Examples include work and heat. These functions are not solely determined by the initial and final states but also by the process followed.
What is a state function and how does it differ from other types of functions in thermodynamics?
A state function in thermodynamics is a property that depends only on the current state of a system, such as temperature, pressure, or volume. It does not depend on the path taken to reach that state. This differs from other types of functions in thermodynamics, such as path functions, which depend on the specific process or path taken to reach a particular state.
What is the difference between a critical point and a triple point in thermodynamics?
In thermodynamics, a critical point is the specific temperature and pressure at which a substance transitions between liquid and gas phases. A triple point, on the other hand, is the unique combination of temperature and pressure at which a substance can exist in all three phases (solid, liquid, and gas) simultaneously.
Which law states that internal energy is function of Temperature?
The First Law of Thermodynamics states that the internal energy of a system is a function of temperature. It describes the relationship between heat transfer, work done, and changes in internal energy. It is a fundamental principle in the field of thermodynamics.
What is the definition of a state function and how does it relate to the keyword "thermodynamics"?
A state function is a property that depends only on the current state of a system, not on how it got there. In thermodynamics, state functions like internal energy and entropy help describe the state of a system and its changes during processes like heating or cooling.
What is difference between path function and point function in thermodyanaMICS?
Path function: Their magnitudes depend on the path followed during a process as well as the end states. Work (W), heat (Q) are path functions.The cyclic integral of a path function is non-zero. work and heat are path functions.Point Function: They depend on the state only, and not on how a system reaches that state. All properties are point functions.The cyclic integral of a point function is zero. properties are point functions, (ie pressure,volume,temperature and entropy).
How is the function differentiable in graph?
If the graph of the function is a continuous line then the function is differentiable. Also if the graph suddenly make a deviation at any point then the function is not differentiable at that point . The slope of a tangent at any point of the graph gives the derivative of the function at that point.
