The law of conservation of energy states that energy cannot be created or destroyed the sum total of energy in a closed system remains unchanged. Energy only changes from one form to another. What is the conservation of energy quizlet? The law of conservation of energy says that energy is neither created nor destroyed.
What is the significance of 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.
Which of the following is true of the law of conservation of energy quizlet?
The correct answer is A. The law of conservation of energy states that the total energy in a system or object remains constant or conserved over time. In this case, energy can never be created nor destroyed during chemical reactions and physical transformations.
What does the law of conservation of mechanical energy state quizlet?
What is the Law of Conservation of Mechanical Energy? Whenever there is no friction acting on a system of objects, the total mechanical energy of the system remains unchanged. You just studied 15 terms!
What does the law of conservation of energy state about energy in a closed system quizlet?
What does the law of conservation of energy state about energy in a closed system? Energy cannot be created or destroyed.
Which statement best describes the law of conservation of matter quizlet?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations.
Which of the following most correctly describes the law of conservation of energy?
Answer and Explanation: The law of conservation of energy states that energy can neither be created nor destroyed, but only converted between various forms.
What is law of conservation of mass quizlet?
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 does the term conservation of energy mean to a scientist check all that apply?
Law of Conservation of Energy. Energy is neither created or destroyed in an isolated system, it just changes from one form to another, or transfers from one part of the world to another. Energy.
Which law states that energy cannot be created or destroyed but can change from one form to another?
First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
What does the law of conservation of energy say about the nature of energy quizlet?
The law of conservation of energy says that energy is neither created nor destroyed. When we use energy, it doesn't disappear. We change it from one form of energy into another.
What does the law of conservation of energy state about energy in a closed system?
The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constant—it can neither increase nor decrease without interference from outside.
Which equation represents the law of conservation of energy in a close system?
EquationsEquationMeaning in wordsE m = K + U E_\text m = K +U Em=K+UThe total mechanical energy of a system is the sum of the total kinetic energy and total potential energy.2 more rows
Which sentence best summarizes the law of conservation of mass?
Which best describes the law of conservation of mass? The mass of the reactants and products is equal and is not dependent on the physical state of the substances.
Which statement summarizes the law of conservation of mass?
The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
Which statement best summarizes the way in which matter and energy interact?
Electromagnetic. Which statement best summarizes the way in which matter and energy interact? Matter and energy interact through four fundamental forces.
What is the main source of energy on Earth quizlet?
Solution. The sun is the primary source of energy for most processes that occur on Earth. The sun's energy is transferred into the Earth's atmosphere and surface using radiation, conduction, and convection.
What is kinetic energy?from quizlet.com
The kinetic energy of an object is the energy it possesses due to its motion. The faster an object moves, the higher kinetic energy it has.
