What is the law of energy and mass conservation?
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
What is the law of conservation of energy state?
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 mass short answer?
The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
What is law of conservation of energy Class 9?
The law of conservation of energy states that energy can neither be created nor be destroyed. Although, it may be transformed from one form to another. If you take all forms of energy into account, the total energy of an isolated system always remains constant.
Who gave the law of conservation of mass Class 9?
Antoine Lavoiser
Answer: Antoine Lavoiser gave the law of conservation of mass.
What is the law of conservation of mass give an 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 is law of conservation of mass Class 9 which chapter?
Class 9 Chemistry Atoms and Molecules. Laws of conservation of mass. Laws of conservation of mass. The law states that mass can neither be created nor destroyed in a chemical reaction i.e. Total masses of reactants is equal to the sum of masses of products and the masses of unreacted reactants.
What is conservation of energy class 11th?
Law of conservation of energy states that energy can neither be created nor be destroyed it can only be transformed from one form to another form.
What is conservation of energy Class 8?
The law of conservation of energy states that “Energy can neither be created nor destroyed but can only be converted from one form to another”. According to the law of conservation of energy, the total energy of an isolated system remains conserved over time.
What is law of conservation of mass Class 9 with example?
Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction. So, the sum of the masses of the reactants and products remains unchanged. For example: CaCO3→CaO+CO2.
What is the example of law of conservation of mass Class 9?
What is law of conservation of mass explain with example class 9?
What is the law of conservation of mass explain it with example class 9?
What is the law of conservation of energy question answer?
The law of conservation of energy states that the total energy always remains constant for an isolated system. The energy is neither created nor destroyed but it can change from one form of energy into the other. These energies can be converted into one another, when the external force is applied and the work is done.
What are the 3 laws of conservation of energy Class 9?
Whenever energy gets transformed,the total energy remains unchanged. According to this law,energy can only be converted from one form to another,it can neither be created or destroyed. The total energy before and after transformation remains same. As ball falls,its potential energy will change into kinetic energy.
What is conservation of energy class 10?
The law of conservation of energy states that “Energy can neither be created nor destroyed but can only be converted from one form to another”.

What is conserved in the law of Conservation of energy?
In any physical change or chemical reaction, mass is conserved; mass can be neither created nor destroyed. Law of Conservation of Energy. a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to anothe.
What is an example of the law of Conservation of mass?
Conservation of Energy and Mass The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed. For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
