3.energy cannot be created neither destroyed, it can only be converted from one place to other
Answer:
answer1. Weight. Mass is quantity of matter determined by Weight.
answer 2.
Isaac Newton, a famous physicist, discovered some basic principles related to energy, mass, and matter. One law that he put forward was the Law of Conservation of Mass or Matter. In physics, mass is known to be in a closed system, which means there cannot be any exchange of matter with the surroundings.
answer 3. 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.
answer 4. Energy can be converted from one form to another. Examples: Gasoline (chemical) is put into our cars, and with the help of electrical energy from a battery, provides mechanical (kinetic) energy. ... Similarly, purchased electricity goes into an electric bulb and is converted to visible light and heat energy.
answer 5. 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.
