What does the first law of thermodynamics state quizlet?
the first law of thermodynamics. states that energy can not be created or destroyed; it can only be redistributed or changed from one form to another.
What is the adiabatic form of the first law of thermodynamics?
change in air temp-pressure change. describes the adiabatic form of the first law of thermodynamics. absolute zero. temperature at which no more energy can be extracted from a substance and no further lowering of its temperature is possible. thermal motion and kinetic motion.
What is the first law of thermodynamics for a closed system?
The first law of thermodynamics can be simply stated as follows: during an interaction between a system and its surroundings, the amount of energy gained by the system must be exactly equal to the amount of energy lost by the surroundings.
Which of the following best describes the first law of thermodynamics?
Which best describes the first law of thermodynamics? Energy is not created nor destroyed but it can change from one energy form to another.
Which statement describes the result of the first law of thermodynamics?
The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.
Why is the first law of thermodynamics important?
The first law of thermodynamics, arguably the most important, is an expression of the principle of conservation of energy. Consistent with this principle, the first law expresses that energy can be transformed (i.e. changed from one form to another), but cannot be created or destroyed.
What are the 1st 2nd and 3rd laws of thermodynamics?
The second law of thermodynamics states that the entropy of any isolated system always increases. The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.
Which best expresses the first law of thermodynamics?
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W.
Who wrote the first law of thermodynamics?
Is the first law of thermodynamics always true?
How can the first law is constantly observed to be true and we call it a scientific law yet we can’t say the equation behind it is true. … The First Law of Thermodynamics, the equation(s) describing the conservation of energy, is “true” in the sense that it is very dependable.
Which best describes the Second Law of Thermodynamics?
energy is not created nor destroyed, but it can change into matter. energy is not created nor destroyed, but it can change from one energy form to another. some useful energy is lost as heat whenever an energy transfer occurs. …
What is the definition of thermodynamics?
Thermodynamics is a branch of physics which deals with the energy and work of a system. It was born in the 19th century as scientists were first discovering how to build and operate steam engines. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments.
