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.

A point function in thermodynamics is a property that depends only on the current state of a system and not on how the system arrived at that state. Examples include temperature, pressure, and internal energy. These functions can be uniquely defined by specifying the state of the system, making them useful for analyzing thermodynamic processes.

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.
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 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.
Is in adiabatic process the work done is independent of path?
Yes, in an adiabatic process, the work done is independent of the path taken because there is no heat transfer involved. The work done is solely determined by the initial and final states of the system.
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 difference between path function and point function in thermodyanaMICS?
A path function in thermodynamics depends on the path taken to reach a particular state, such as work and heat, while a point function depends only on the state of the system, like temperature, pressure, and internal energy. Path functions are not uniquely determined by the initial and final states, while point functions are determined by the state variables of the system at a specific moment regardless of how the system reached that state.
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.
The depth of a lake at a center point which is a function of the distance of that point from shore?
The depth of a lake at a center point is a function of the distance of that point from shore.
What is the zero of a function and how does it relate to the functions graph?
A zero of a function is a point at which the value of the function is zero. If you graph the function, it is a point at which the graph touches the x-axis.
Can a constant function be one to one?
Yes - if the domain is a single point. Not much point in having such a function, but it can exist.
A wireless access point can function as which type of shared medium?
A wireless access point can function as an access point and it can also be used as a repeater....
How is heat tranferred by conduction?
By the principle of thermodynamics, the heat travels from one body which in contact with the other, till the point where both the bodies acquire same temperature, so conduction works in sync with thermodynamics where both bodies acquire same temperature.
How is the thermodynamics process related to the 1st law of thermodynamics?
