Question

what is the first low of thermodynamics​

Answer 1

the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy.

Answer 2

Answer:

Hope this helps you...!!!

Explanation:

The first law of thermodynamics relates to heat, internal energy, and work.

The first law of thermodynamics, also known as the law of conservation of energy states that energy can neither be created nor destroyed, but it can be changed from one form to another.

First Law of Thermodynamics:

According to this law, some heat given to the system is used to change the internal energy while the rest is used in doing work by the system.

It can be represented mathematically as

ΔQ = ΔU + W

Where,

ΔQ is the heat given or lost

ΔU is the change in internal energy

W is the work done

We can also represent the above equation as follows,

ΔU = ΔQ − W

So we can infer from the above equation that the quantity (ΔQ – W) is independent of the path taken to change the state. Further, we can say that internal energy tends to increase when the heat is given to the system and vice – versa.
