What would happen to the amount of matter on earth if mass were not conserved during changes of state

According to Einstein, mass can be transformed into forms like energy and then energy can convert back to mass hence it is conserved.

It says that mass of an object has nothing to do with the changes in states however a big mass would be needed more energy and power to convert or change states.

So it can be said that during change of states, there will appear no impact on the mass of objects it will remain same but if changes appear in the mass, the earth will shrink with time.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.
