State the First and Second Laws of Thermodynamics and explain why they are important in understanding your ability to extract and use energy resources?

Answer 1

The first law states that neither matter nor energy can be created or destroyed

The second law states that everything tends toward disorder ie. falls apart, fades, withers, erodes, etc.

I like the versions:

1st: You can't get something for nothing

2nd: Not only that, you can't even break even

Answer 2

FIRST LAW OF THERMODYNAMICS

*the total heat energy applied to the system is equal to the sum of the change in internal energy of the system and the work done by the system.

SECOND LAW OF THERMODYNAMICS (entrophy)

*no process in w/c the total entrophy decreases is possible when all the systems taken apart in the process are considered.

THIRD LAW OF THERMODYNAMICS

*The entrophy of a perfect crystal of a substance at the absolute temp. is zero.

Answer 3

First Law of Thermodynamics is also known as Conservation of Energy.

Second Law of Thermodynamics means that useful energy is continuously being converted into unusable energy - there are irreversible processes in our Universe, with respect to energy.

Answer 4

First law is conservation of energy. You can't create or destroy energy.

Second law - there are several formulations for it, but since you are asking about energy, the idea is that useful energy can get converted into useless, or unusable, energy - energy that can no longer be converted arbitrarily into other kinds of energy.

It is important to know these laws, since otherwise, you might try some queer things, like getting energy out of nothing. Once you understand that this isn't possible, you can concentrate on things that do work.

Answer 6

The first law of thermodynamics states that you can't create or destroy energy.

The second law of thermodynamics has been formulated in several ways; one of them is that useful energy is constantly being converted to useless energy - in other words, with respect to energy, there are irreversible processes in nature.
