Heat and work are path functions because they depend on the specific path taken during a thermodynamic process. The amount of heat transferred or work done can vary depending on the specific conditions and intermediate states encountered during the process. This is in contrast to state functions, such as internal energy and enthalpy, which only depend on the initial and final states of the system and are independent of the path taken. Mathematically, path functions are represented as integrals, reflecting the dependence on the specific path followed.

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 heat capacity a path function?
Well, honey, heat capacity is a path function because it depends on the specific process or path taken to reach a certain state. It's all about how much heat is needed to change the temperature of a substance, and that can vary depending on the route you take. So, in a nutshell, heat capacity doesn't give a damn about the destination, it's all about the journey.
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 are state functions in thermodynamics and how do they differ from path functions?
State functions in thermodynamics are properties that depend only on the current state of a system, such as temperature, pressure, and internal energy. They do not depend on the path taken to reach that state. Path functions, on the other hand, depend on the specific path taken to reach a particular state, such as work and heat.
Which of the following is the most basic function of energy?
The most basic function of energy is to enable work to be done. Energy is the capacity to do work or produce heat. This allows for movement, growth, and other processes in living organisms and systems.
How heat is a path function?
Heat capacity is NOT a path function. It is a STATE function. It depends on the phase of the material, the temperature and the pressure. Usually heat capacity is known at some particular condition and then a calculation is required to estimate it at the condition of interest. Performing these calculations should always result in the same final value no matter the path you took to get to the value - hence it is a STATE function rather than PATH. Path functions would be things like WORK and HEAT (for which the state function "heat capacity" might be used in the calculations)
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.

Why work and heat transfer are not property of the system?
irstly from Thermodynamics point of view, we need to call heat as Heat transfer. Both Heat and work transfer are energies in transit. They come into picture only when a process is taking place. Also the quantity of heat transfer depends on the type of process or path followed. So Heat Transfer is a path function but not a property(which is a point function). 📷 In case of properties, the difference in properties (here P2-P1 or V2- V1)between state 1 and state 2 always remains same irrespective of the path followed. So properties are called Exact Differentials or Point functions. But in case of Heat transfer and Work transfer, the quantity of heat and work transfer between state 1 and state 2 depends on the path followed. Therefore heat and work transfer are not exact differentials,they are Inexact differentials or path functions.
Are heat and work path functions?
No, heat and work are not path functions. Heat and work are energy interactions between a system and its surroundings that depend on the process taken, not just the initial and final states. Path functions are properties whose values depend on the path followed to reach that state, such as change in temperature.
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.
Heat and ac work but temperature gauge does not function?
Bad gauge or defective coolant temperature sensor
Why do catalyst work without adding heat?
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
