Question

15) The diagram below represents the sequence of events (steps 1 through 10) resulting in the production of a D' meson and a D* meson. An electron and a positron (antielectron) collide (step1), annihilate each other (step 2), and become energy (step 3). This energy produces an anticharm quark and a charm quark (step 4), which then split apart (steps 5 through 7). As they split, a down quark and an antidown quark are formed, leading to the final production of a D' meson and a D* meson (steps 8 through 10).
Which statement best describes the changes that occur in this sequence of events?
(1) Energy is converted into matter and then matter
is converted into energy.
(2) Matter is converted into energy and then energy
is converted into matter.
(3) Isolated quarks are being formed from baryons.
(4) Hadrons are being converted into leptons.

Answer 1

A statement which describes the changes that occur in this sequence of events is: 2. matter is converted into energy and then energy is converted into matter.

What is the law of conservation of matter?

The law of conservation of matter (LOCOM) states that mass can neither be created nor destroyed in any chemical reaction.

Similarly, the energy possessed by a matter can neither be created nor destroyed, but it can only be converted from one energy form to another.

In this context, we can logically deduce that a statement which best describes the changes that occur in this sequence of events is that matter is converted into energy and subsequently, energy is converted into matter.
