Which of the following statements best describes the law of conservation of energy?
Answer: The law of conservation of energy is the preserved form of energy. Option (1) is correct that is the total amount of energy in the universe remains constant. Because energy is conserved.
Which statement is true in relation to 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 is the law of conservation of energy quizlet?
law of conservation of energy. the law that states that energy cannot be created or destroyed but can be changed from one form to another. thermal energy. total amount of energy associated with the random movement of atoms and molecules in a sample of matter.
Which definition best describes the term activation energy quizlet?
Which is the best definition of activation energy? the energy required to end a chemical reaction. the energy required to bind a substrate to an active site. the energy required to break the bonds of reactant molecules.
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.
What is the relationship between work and power?
Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.
What is the law of conservation of energy in simple terms?
In physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. … For instance, chemical energy is converted to kinetic energy when a stick of dynamite explodes.
What does law of conservation of energy verify?
Law of conservation of energy states that:− Energy can neither be created nor be destroyed. Energy transforms from one form to another form and, potential energy+ kinetic energy= constant. Proof:− At point A.
What do you mean by conservation of energy?
Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The first kind of energy to be recognized was kinetic energy, or energy of motion.
Why law of conservation of energy is important?
This law is very important because it is a very easy way to figure out important information about an object. For example, if you know an object’s mass and initial height, you can find its initial potential energy, which is all the energy that it starts with.
What do we mean by conservation of energy quizlet?
Law of Conservation of Energy. the amount of energy you start with is the amount of energy you end with; the amount of energy always stays the same though its form may change. Magnetism.
What does energy conservation require?
Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less).
What definition best describes the term activation energy?
The activation energy (Ea ) is defined to be the minimum kinetic energy required that a system must have to initiate a reaction (whether chemical or nuclear) and/or any physical phenomena.
How do you explain activation energy?
Activation energy, in chemistry, the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.
