The energy of the universe is constant. That what mentioned by the first law of thermodynamics,
Does this mean that AE is always equal to zero?
Select one:
a. Yes, AE = 0 at all times, which is why q = -W
b. No, AE does not always equal zero because it refers to the system's internal energy, which is
affected by heat and work.
c. No, AE never equals zero because work is always being done on the system or by the
system.
d. No, AE does not always equal zero, but this is only due to factors like friction and heat.
e. No, AE never equals zero because energy is always flowing between the system and
surroundings.
