Choose the correct description, of what happens to the electron speeds in a more massive white dwarf. Choose the correct description, of what happens to the electron speeds in a more massive white dwarf. As the mass of a white dwarf increases, the pressure must increase to resist gravity. To do this, the electrons must move faster. As the mass of a white dwarf increases, the pressure must decrease to resist gravity. To do this, the electrons must move faster. As the mass of a white dwarf increases, the pressure must decrease to resist gravity. To do this, the electrons must move slower.
