Question

Identify the three statements from the list below that BEST describe the first law of thermodynamics.

A. The energy gained or lost by a system must equal the energy lost or gained by the surroundings.

B. The total energy of the universe is decreasing.

C. The work done by a system equals the work done on the surroundings.

D.ΔE = E_final – E_initial

E. Heat released by the system is absorbed by the surroundings.

F.ΔE = q + w

G.Energy can be neither created nor destroyed, but it can change from one form to another.

H.ΔE_univ = ΔE_sys + ΔE_surr = 0

I. The sum of all of the kinetic and potential energies of all of the components of a system is constant.

It says which 3 best describe the first law of thermodynamics. I've tried all different combinations. One of the hints it gives me says "The first law of thermodynamics describes the energy content of the universe. While there are many true statements here, only three directly relate to the first law of thermodynamics and the universe. Many of the other true statements relate to systems." Multiple students have asked this, and the answers are all incorrect. I'll try one more time before I settle for a 89%.

Answer 1

Answer : A , F, I are describing the best choices for FLOT.

SInce total energy in the universe is constant. It only changes from one form to another.
