Law Of Conservation Of Matter And Energy
What is Law Of Conservation Of Matter And Energy?
The law of conservation of matter and energy states that the total amount of matter and energy in a closed system remains constant; matter and energy can be converted from one form to another but cannot be created or destroyed. In ordinary chemical reactions, mass is conserved separately (law of conservation of mass), but in nuclear reactions matter can be converted to energy according to Einstein's equation E = mc². This law is one of the most fundamental principles of physical science.
