Question

Which of the following statements best describes the first law of thermodynamics?

06 Question ( point) Q See page 212 9th attempt See Periodic Table See Hint Which of the following statements best describes the first law of thermodynamics? Choose one or more: A. The energy gained or lost by a system must equal the energy lost or gained by the surroundings. B. The work done by a system equals the work done on the surroundings C. The sum of all of the kinetic and potential energies of all of the components of a system is constant E. AE-Ehnal-Einitial F. The total energy of the universe is decreasing. G.Energy can be neither created nor destroyed, but it can change from one form to another H. Heatreleased by the system is absorbed by the surroundings.

Explanation / Answer

A). This descibes the first law of thermodynamics--- The energy gained/lost by a systemis is equal to the energy lost/gained by the surroundings

B). This descibes the first law of thermodynamics----- equation in A). represents the work done by system equals to the work done on the surroundings.

C). Their sum can not be constant it may vary so this statement can not descibes the first law of thermodynamics

D). The energy in a system may change, but it must be complemented by a change in the energy of its surroundings to balance the change in energy. so This descibes the first law of thermodynamics

E). The change in the internal energy of a system is equal to the difference between the final and initial energies of the system This descibes the first law of thermodynamics

F). This can not descibes the first law of thermodynamics because The total amount of energy and matter in the Universe remains constant

G). we know that this is main statement of first law of thermodynamics is Energy cannot be created or destroyed, it can only be changed from one form to another so This descibes the first law of thermodynamics

H).This descibes the first law of thermodynamics

I). This equation descibes the first law of thermodynamics
