Answer to Question 1

e

Answer to Question 2

A normal star is supported by energy flowing outward from its core, but a white dwarf can't generate energy by nuclear fusion. It has exhausted its hydrogen and helium fuels and converted them into carbon and oxygen. When a star collapses into a white dwarf, it converts gravitational energy into thermal energy. Its interior becomes very hot, but it can't get hot enough to fuse its carbon-oxygen interior. Instead the star contracts until it becomes degenerate. The white dwarf is supported against its own gravity by the pressure of its degenerate electrons.
