Conservation of quantity refers to the principle that certain quantities, such as mass, energy, or momentum, are always conserved or remain constant in a closed system.
Conservation of quantity is important in science because it allows us to make predictions and understand the behavior of systems. It also helps us to identify and understand the laws of nature.
Some examples of conserved quantities include mass, energy, momentum, charge, and angular momentum.
We can determine which quantity is conserved in a system by analyzing the physical laws and principles that govern that system. In most cases, there will be a specific equation or principle that describes the conservation of a certain quantity.
No, a conserved quantity cannot be lost or gained in a closed system. It can only be transferred or transformed into another form, but the total amount will always remain constant.
