| Q. |
Which of the following laws validates the statement that matter can neither be created nor destroyed? |
| A. | Law of conservation of energy |
| B. | Le Chatelier's Principle |
| C. | Law of conservation of mass |
| D. | Law of osmosis |
| Answer» C. Law of conservation of mass | |
|
Explanation: The law of conservation of mass, also known as the principle of mass/matter conservation, states that the mass of an isolated system (closed to all transfers of matter and energy) will remain constant over time. This principle is equivalent to the conservation of energy: when energy or mass is enclosed in a system and none is allowed in or out, its quantity cannot otherwise change over time (hence, its quantity is "conserved" over time). |
