## Which of the following quantities is not a state function?

Answer: Work is not state function as it doesn’t depend on the path followed..

## What are examples of path functions?

Examples of path functions include work, heat and arc length. In contrast to path functions, state functions are independent of the path taken. Thermodynamic state variables are point functions, differing from path functions.

## Why Heat is not a state function?

A state function is independent of pathways taken to get to a specific value, such as energy, temperature, enthalpy, and entropy. Enthalpy is the amount of heat released or absorbed at a constant pressure. Heat is not a state function because it is only to transfer energy in or out of a system; it depends on pathways.

## Which quantities are state functions?

The thermodynamic state of a system refers to the temperature, pressure and quantity of substance present. State functions only depend on these parameters and not on how they were reached. Examples of state functions include density, internal energy, enthalpy, entropy.

## Why work is not a thermodynamic property?

Why are work and heat not thermodynamic properties? Work and heat are not defined by the state of the system. If you have a system in a particular state, it does not have a certain amount of heat and a certain amount of work. … The amount of heat and work are different depending on how you change the state of the system.

## Which is not a state function?

Heat and work are not state functions. Work can’t be a state function because it is proportional to the distance an object is moved, which depends on the path used to go from the initial to the final state.

## Which of the following is a state function?

List of state functions is pressure, temperature, volume, mass, internal energy, Gibb’s free energy, entropy. … Those functions which do depend on the path from two points are known as path functions.

## Is Q state function?

Answer. Solution for your first query, This is total energy called internal energy E = q+w. It is a state function as it depends on the intial and final state and independent of the path.

## Which one is not thermodynamic state function?

Heat (q) and work (W) are not state functions being path dependent. A state function is the property of the system whose value depends only on the initial and final state of the system and is independent of the path.

## Is enthalpy a state function?

As represented by the solution to the integral, enthalpy is a state function because it only depends on the initial and final conditions, and not on the path taken to establish these conditions. Therefore, the integral of state functions can be taken using only two values: the final and initial values.

## Is work done a thermodynamic function?

By an external system that lies in the surroundings, not necessarily a thermodynamic system as strictly defined by the usual thermodynamic state variables, otherwise than by transfer of matter, work can be said to be done on a thermodynamic system.

## Why Entropy is a state function?

State function is path independent,it depends only initial and final point. … Entropy is disoderness,which is also path independent and depend on it initial and final points.So entropy is a state function.

## Why work done is not a state function?

State functions depend only on the state of the system, not on the path used to get to that state. … Heat and work are not state functions. Work can’t be a state function because it is proportional to the distance an object is moved, which depends on the path used to go from the initial to the final state.

## Is pressure a state function?

Pressure is a measure of the average force exerted by the constituent molecules per unit area on the container walls. pressure does not depend on the path of the molecules and thus it is a state function.

## Does entropy increase with temperature?

Entropy increases as temperature increases. An increase in temperature means that the particles of the substance have greater kinetic energy. … Entropy generally increases in reactions in which the total number of product molecules is greater than the total number of reactant molecules.

## Which of the following is not a state variable?

The correct option is B) Temperature, pressure, volume are examples of state variables. The path variable is defined as the variable which depends on the specific value that is reached. Distance and displacement are examples of path variables.
