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. …
Which is a correct statement of the second law of thermodynamics?
The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time, and is constant if and only if all processes are reversible. Isolated systems spontaneously evolve towards thermodynamic equilibrium, the state with maximum entropy.
Which statement most accurately describes the law of conservation of energy?
The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it’s added from the outside.
What does the second law of thermodynamics state about energy quizlet?
State the Second Law of Thermodynamics. The entropy of the universe must always increase for an spontaneous reaction. The second law of thermodynamics states that the total entropy can only increase over time for an isolated system, meaning a system which neither energy nor matter can enter or leave.
What is the second law of thermodynamics in simple terms?
The second law of thermodynamics states that entropy, which is often thought of as simple ‘disorder’, will always increase within a closed system. Ultimately, this is one of the key elements dictating an arrow of time in the Universe.
What does the second law state?
The second law states that the acceleration of an object is dependent upon two variables – the net force acting upon the object and the mass of the object.
Which of these is impossible by the second law of thermodynamics?
The Second Law of Thermodynamics(first expression): Heat transfer occurs spontaneously from higher- to lower-temperature bodies but never spontaneously in the reverse direction. The law states that it is impossible for any process to have as its sole result heat transfer from a cooler to a hotter object.
Which statement best describes the Law of Conservation of Mass?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Which statement describes the law of conservation of energy quizlet?
The law of conservation of energy states that energy is not created or destroyed during chemical reactions. The total amount of energy in the reactants, plus the energy absorbed during the reaction, must be equal to the total energy of the products.
What is the relationship between potential and kinetic energy in chemical reactions?
~Potential energy transforms into kinetic energy when changes in the bonds of reacting substances affect the motion of the atoms within them. ~Kinetic energy transforms into potential energy when moving molecules bump into each other and cause the position of their bonds and atoms to change.4 мая 2020 г.
What are the two laws of thermodynamics?
The first law, also known as Law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.
What is the premise of the second law of thermodynamics quizlet?
2nd law of thermodynamics. The principle stating that every energy transfer or transformation increases the entropy of the universe. Ordered forms of energy are at least partly converted to heat.
