Hi guys in this article we study the topic Difference Between Availability and Energy it is important point in thermodynamics so let's start without wasting of time further information,

Availability and energy are two distinct concepts, especially in the context of physics and thermodynamics. 

Difference Between Availability and Energy

Energy:

It exists in various forms such as kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy (stored in bonds of atoms and molecules), etc.

Energy can be converted from one form to another according to the laws of thermodynamics, particularly the conservation of energy principle.

SI unit = joule (J).

Availability (known as exergy):

Availability refers to the maximum useful work that can be obtained from a system as it comes into equilibrium with its environment.

It represents the portion of energy that can be converted into useful work under specific conditions.

Availability is dependent not only on the quantity of energy but also on the quality and temperature of that energy. For instance, high-temperature energy is more available than low-temperature energy.

Exergy analysis is often used to quantify availability in engineering and thermodynamics applications.

Availability is particularly important in assessing the efficiency of energy conversion processes.

Unit of availability is joule (J),

it represents a measure of useful work.

Differences:

Nature: Energy is a general concept referring to the capacity to do work or produce heat, whereas availability specifically refers to the potential for useful work.

Use: Energy can be in various forms and is used for various purposes, whereas availability is a measure of how much useful work can be obtained from a system's energy.

Conversion: Energy can be converted from one form to another without loss (according to the conservation of energy), while availability is a measure of the quality of energy and how much of it can be converted into useful work.

Difference Between Availability and Energy

Sr. No	Availability	Energy
1	Availability is function of surrounding and system.	Energy is function of state of system only.
2	Temperature increases with drop at low temperature.	Energy increases with rise in temperature.
3	It does not obey law of conservation of energy.	It obeys law of conservation of energy.
4	Availability calculated by surroundings are specified.	Energy calculated by specified factor.
5	It is positive value of ideal vacuum.	It is zero at Idle vacuum.

So in this article we learned the topic Difference Between Availability and Energy Hope you understand well.
