Which statement describes the law of conservation of energy?

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.

How do you describe the law of conservation of energy?

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 is the law of conservation of energy definition for kids?

One such law is called the conservation of energy. This law says that the amount of energy in a system never changes. No new energy is created, and no old energy is destroyed.

Which statement is an example of the law of conservation of energy?

Terms in this set (10) What is the best example of the law of conservation of energy? If a pendulum is one meter off the ground at one end of its swing, it can never be more than one meter (The law of conservation of energy states that energy cannot be created or destroyed.

Which has the most kinetic energy?

Plasma

What is the best example of potential energy?

Examples of Gravitational Potential Energy

When something has a high position, its gravitational potential energy is high. For example, a book on a high bookshelf has a higher gravitational potential energy than a book on the bottom shelf because it has farther to fall.

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 do you mean by energy conservation?

Energy conservation is the decision and practice of using less energy. Turning off the light when you leave the room, unplugging appliances when they’re not in use and walking instead of driving are all examples of energy conservation.

What is conservation of energy explain with an example?

Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. … For example, when a pendulum swings upward, kinetic energy is converted to potential energy.

Why is the law of conservation of energy 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 is the law of conservation of matter and energy?

The law of conservation of matter and energy states that matter is neither created nor destroyed but conserved. Humans do not have the ability to create or destroy matter (atoms) or energy. They can only rearrange the matter and energy. For example, an oxygen atom will cycle through a living system.

What is law of conservation of mass explain with example?

The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted.

What are the two main types of energy?

After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. ​Kinetic energy is defined as the energy of a moving object.

What is a example of conservation?

An example of conservation is a program to try to preserve wetlands. An example of conservation is a program to try to save old buildings. An example of conservation is an attempt to minimize the amount of electricity you use by turning off lights when you leave a room.
