According to Albert Einstein, mass and energy are equivalent. That means that mass and energy can be converted into each other according to the famous equation, $E={ m }^{ }{ c }^{ 2 }$, where $E$ is energy, $m$ is mass, and $c$ is the speed of light.

Which of the following are examples of mass-energy equivalence?

A

A furnace burns a fuel and creates energy until the fuel is depleted. You start with mass and create energy from it.

B

A nuclear reactor converts mass to energy in a fission process.

C

An endothermic reaction requires the addition of energy in order to create the final product. This energy is converted into the mass of the product.

D

When matter and antimatter meet, they annihilate each other and create energy from their mass.
