Total energy (kinetic plus internal) is also conserved. Butt the conservation of total energy is not related to the conservation of mass. The one doesn't imply the other in pre-relativity Physics. (b) I recommend Taylor/Wheeler: 𝑆𝑝𝑎𝑐𝑒𝑡𝑖𝑚𝑒𝑃ℎ𝑦𝑠𝑖𝑐𝑠, as an excellent introduction to the concepts of Special Relativity, including mass and energy.

I like this answer, but could you please provide a reference to a source that says the same thing? Thanks.
