Entropy is the spreading out of energy, and energy tends to spread out as much as possible. The total mechanical energy is said to be conserved. Hence according to the law of conservation of energy the total energy remains constant. The correct option is D. Due to mass-energy equivalence, the Planck constant also relates mass to frequency.. However, if we assume that dark energy is indeed the vacuum energy, more energy would be contained in our universe as the universe is expanding. Energy can only be transferred from system to surrounding or surrounding to system in various forms, but it can never be destroyed or created. 7. Answer (1 of 10): There is no requirement for the energy of the universe to remain constant. Thus the total amount of energy in the universe is constant. In essence, energy can be converted from one form into another. Mass and energy in the universe remains constant under all current "Accepted" cosmological models (although not some of the newer proposed theories). Since the excitation power remains constant, much higher total system efficiency is expected though the efficiency of the SPG as computed above will remain constant at 211.8%. Biology. Wiki User.

Entropy is a measurement of the disorder of material/energy. We observe that the universe is expanding. But energy density is the more useful thing to talk about anyway. Another interesting theory is that it is used in maintaining the vacuum energy density of the expanding universe. C) The total entropy of an isolated system cannot decrease: D) Energy can only be converted from one form to another: Heat evolved by the system is negative. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. * Spacetime is dynamical i.e. It will have the same ratio of dark energy, dark matter, normal matter, neutrinos, and radiation as our Universe, and, perhaps most importantly, all of the fundamental constants will have the same . The total amount of entropy in the universe is increasing. V. Efficiency is a measure of the ratio of work done to work available. • Therefore, the total energy of the universe is a constant. Energy exists in many different forms. Dark Energy makes up a large majority ot the total content of the universe, but this was not always known. (ignore any input/output to the system: refrigerator + box. While energy may change in form (heat, work, etc.) True or False: The total energy of the universe remains constant. b. the reaction is spontaneous. According to the first law of thermodynamics, energy can be transferred from place to place or changed between different forms, but it . The easy answer is simply no, energy is not conserved at all. 2.Given that DHvap is 52.4 kJ/mol, and the boiling point is 83.4°C, 1 atm, if one mole of this substance is vaporized at 1 atm, calculate DSsurr. Of course the speed will not be the same, as speed is a scalar. The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. = (1 − 0 ) 2 (1.3) For a particle moving in a gravitational field, its total energy E is conserved, so it is a constant. [T]he total energy of the universe is increasing such that the energy inherent of space-time is kept constant as the universe expands. The usable energy in the universe is decreasing. That what mentioned by the first law of ?thermodynamics, Does this mean that AE is always equal to zero اخترأحد الخيارات a. C) The total energy of the universe increases, while the entropy decreases. So the total energy of particle moving in the gravitational field is formula (1.3). As a system becomes more disordered, the lower its energy and the higher its entropy. 3. Even though energy and matter can change into one another, the amount of energy and the possible energy (matter) stays the same. D) The total energy of the universe is constant, but the entropy is increasing. In other words, there has always been, and always will be, exactly the same amount of energy in the universe. Even so, this statement is not of terribly practical utility, so we can restate the first law in a more useful form . Drinking cleansing teas: drink detoxifying teas, kombucha, energy-infused waters, etc. The section after that will make plausible the suggestion that the total energy could be zero by means of a well defined calculation using a Newtonian cosmology. it would seem like the answer would have to be yes, since (1) enthalpy change represents the heat exchange between the system and the surroundings, and there is nothing "outside" the universe, and (2) in the equation h = u + p v, the matter in the universe is surrounded by a vacuum so p = 0 and that term disappears, so the enthalpy is just the … The universe is dominated by dark energy, which is consistent with a cosmological constant Λ. So the universe can start off with zero energy and still create matter. The first law of thermodynamics, also called the Conservation of Energy law, says that the total energy of the universe is constant. first law of thermodynamics. The universe consists of the system as well as the surrounding together.
