- 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).

MaxineA 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.

What is the difference between one point of the wave to another point of the wave?
The difference between one point of a wave and another point is the phase difference, which reflects how much the wave has shifted in terms of position or time. This phase difference determines whether the points are in phase (crest aligns with crest or trough with trough), out of phase (crest aligns with trough), or somewhere in between.
The difference between set-point and the process variable is called?
The error is the difference between the set-point and the process variable. It represents the deviation that the controller needs to correct in order to maintain the process variable at the desired set-point.
What is the phase difference between points e and f?
The phase difference between points e and f is the difference in the position of their respective waveforms at a given point in time.
True or false the difference between water freezing and water boiling in the Fahrenheit scale is 100?
True. The difference between the freezing point (32°F) and boiling point (212°F) of water in the Fahrenheit scale is 180°F.
What is the difference between frost point and dew point?
The main difference between frost point and dew point is the temperature at which they occur. Frost point is the temperature at which water vapor in the air turns directly into ice crystals, while dew point is the temperature at which water vapor in the air condenses into liquid water droplets. Frost point typically occurs at colder temperatures than dew point.
