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 option 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 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 concept of conservation of energy?
Energy may be converted from one form to another. The principle of conservation of energy states that the total amount of energy remains the same in such conversions, i.e. energy cannot be created or destroyed.
What is the law of conservation of mass easy definition?
The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system’s mass cannot change, so quantity can neither be added nor be removed.
What are the 3 laws of conservation?
In physics, a conservation law states that a particular measurable property of an isolated physical system does not change as the system evolves over time. Exact conservation laws include conservation of energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.
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 the law of conservation state?
Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. … For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.
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.
