Question

Is the 1st law of thermodynamics just law of conservation

Answer 1

Answer:

Explanation:

What is the first law of thermodynamics?

We know about internal energy, heat, and work done for a system in thermodynamics, but how are these quantities related to each other. The laws of thermodynamics, give us the guidelines for inter-conversion of energy from one form to the other. The history of thermodynamics dates back to the time when first heat engines were designed for the extraction of water from mines. The studies for improving the efficiency and output of these engines continued for a longer time. The first law of thermodynamics was conceived by a trial and error method that stretched over a period of fifty years.

First law of thermodynamics statement:

The thermodynamics first law states that ” The total energy of an isolated system is constant.”

A close examination of this statement suggests that the first law of thermodynamics is nothing but conservation of energy. The basis for the development of this law is the conservation of energy. As per the thermodynamic approach, this law is stated as the internal energy change of any closed system is given by the difference between the heat stored in a system and the work done by it. An equivalent way of stating the first law of thermodynamics is that perpetual motion machines, which can indefinitely do work without any energy source are impossible as it violates the conservation of energy and thermodynamics first law.

Answer 2

Explanation:

First law of Thermodynamics :-

→ According to this La energy can neither be created nor be destroyed. So you in any physical or chemical process Total energy of universe is constant .

°•° ∆U = q + W.
